Subject: [Caml-list] Question about objects and method overriding

Dear caml-list,

With records, one can functionally update a field e.g. as

{ r with some_field=new_value }

And new_value may, of course, be a function.

With objects, is there similar functionality? e.g. can I write something like

{{ myobj with method some_method=new_method }}

?

Of course, I could copy the methods from myobj explicitly into a new
object (and set some_method to new_method), but I might not know all
the methods available on myobj, and even if I do this becomes
textually extremely verbose.

Of course, new_method cannot directly refer to self etc. Basically I
am using objects in a similar way to records, and would like to use
this functional record update feature.

Thanks

Tom
