Maybe there could be another 3.07 version release with or without
changing the version number and before to much experimental features
went into CVS ?

Having been bitten by this bug myself (which appears to hit labeled
arguments in general, not just optional arguments), I'd be quite eager for
a rerelease of 3.07 (3.07.1?) that fixes this problem. It's a pretty
serious bug, especially if camlp4 is to be thought of as a real part of
the core system.

I second that. Hopefully, OCaml 3.07+beta2 is still available, because it
is the only version that can compile the CVS branch of CDuce... Please
don't remove it!

Then you should imperatively submit a bug report reproducing the
problem. The CVS version is supposed to be fixed for all camlp4 bugs
that have been reported up to now.

I have applied de patch and the problem persists, rebuilding
3.07 with the last hours CVS sources yields same results, so I've
reinstalled 3.07+beta2.

Thanks for your answer, the add of explicite parenthesis allows the
compilation to work fine. It's a bit long to add parenthesis in all the
sources, but I hope the next release will fix this bug.

After another bug report, it seems that a parsing bug went into camlp4
just before the release :-(
Camlp4 Parsing version 3.07
# fun (f : ?x:int -> bool -> float) -> f true;;
This expression has type bool but is here used with type ?x:int -> bool
# fun (f : ?x:int -> bool -> float) -> f;;
- : ((?x:int -> bool) -> float) -> (?x:int -> bool) -> float = <fun>
This is apparently a priority problem.
A workaround is to explicitly add parentheses.
# fun (f : ?x:int -> (bool -> float)) -> f true;;
- : (?x:int -> bool -> float) -> float = <fun>
There is no fix for camlp4 itself yet.

I don't remember introducing any change at that level.
Your exemple is not detailed enough that I can infer the real cause.
You should submit a bug report including a minimal set of sources
producing the error.
A reasonable hypothesis is that you have fallen into the
non-principality of optional arguments (which is explained in the
manual). Try compiling your sources with ocaml 3.06, adding the option
ocamlc -principal.
If it tells you that some use is not principal, then the cause is the
increased polymorphism in 3.07: some type sharing appearing in 3.06
does not appear in 3.07. In general more polymorphism is a good thing,
but with non-principal features it may introduce incompatibilities.
Here, this would mean that you need another type annotation elsewhere.
Byt the way, why do you write
(sol#scalarizingFunction : ?weightVector':Solution.cWeightVector -> Solution
cPoint -> float)
rather than "(sol : #Solution.solution)#scalarizingFunction" ?

Hi all,
I've just downloaded ocaml 3.07 and compil it. But when I try to compil old
programs, I encounter some problems with optional arguments in methods.
In fact I have the following method in a class called Solution:
method scalarizingFunction ?weightVector' referenceSolution =
match weightVector' with
None -> self#doScalarizingFunction referenceSolution
| Some y -> self#doScalarizingFunction' y referenceSolution
where referencePoint is a Solution.cPoint type object, and weighVector' a
Solution.weightVector type object.
and in another source file, I have the call:
let newScalarizingFunctionValue =
(sol#scalarizingFunction : ?weightVector':Solution.cWeightVector -> Solution
cPoint -> float) referencePoint in .....
With ocaml 3.06, It compiles fine, but with ocaml 3.07 I'va got the
following error:
ocamlc -I ../Common -I ../Exact -I ../TS -I ../SA -I ../EA -I ../HGA -g -pp
camlp4o unix.cma -c ../SA/mOSA.ml
File "../SA/mOSA.ml", line 64, characters 135-149:
This expression has type
Solution.cPoint =
< augment : Solution.cPoint -> Solution.cPoint -> unit;
compare : Solution.cPoint -> Global.comparison; copy : Solution.cPoint
distance : Solution.cPoint ->
Solution.cPoint -> Solution.cPoint -> float;
get_OV : int -> float; get_OV_size : int;
linearScalarizingFunction : Solution.cWeightVector ->
Solution.cPoint -> float;
load : char Stream.t -> unit;
minmaxScalarizingFunction : Solution.cWeightVector ->
Solution.cPoint -> float;
save : out_channel -> unit; set_OV : int -> float -> unit >
but is here used with type
?weightVector':Solution.cWeightVector -> Solution.cPoint
make: *** [../SA/mOSA.cmo] Error 2
Is there any changes with the use of optional arguments for methods ?
I didn't find any clue in the ocaml 3.07 documentation.
Thanks you for your help.
Vincent
