Subject: UsingPolymorphic Variants
Date: Sat, 1 Oct 2005 17:06:09 -0700 [thread overview]
Message-ID: <20051002000609.GA30761@anthony.ics.uci.edu> (raw)
Basic Question:
Why aren't polymorphic variants coerced by default?
My Situation:
I am automatically generating some code that uses polymorphic variants
extensively. The inferred types are very complicated. Unfortunatly, at
some points in my code coercions are needed for it to compile. Since I
don't have the types available when I generate the code (and I don't
think it's possible to refer to inferred types in coercions) I can't
coerce explicitly. I'd like to be able to say something like:
... f (x: type_of_x :> type_expected_by_f) ...
Anyway, that's why I'm wondering why the compiler doesn't automatically
coerce or, at least, offer a switch with this functionality.
Thanks for your time,
Chris
