- Lazy constructor and function can not be matched ... and this is ennoying

I saw a post recently about lazy constructor and I can not write the
camlp4 extension I want because of the second limitation ...

It may be not clear what I mean by matching a function (looks impossible
;-). I mean something like

pattern <= expr expr expr       is a pattern

and a function f is matched by

p <= e1 ... eN      iff     f e1 ... eN is matched by p

(I do not care about the final syntax ...)

I know there is a BIG problem of ambiguity in the evaluation order for
complex pattern matching ...
The user should be warned about that. But this would not be a problem
for the application I have in mind.
