Subject: [Caml-list] Comparison of functional values
Date: Tue, 6 Mar 2001 22:51:54 +0100 [thread overview]
Message-ID: <15013.23546.425793.7568@akasha.ijm.jussieu.fr> (raw)
Hello list,
I wanted to build a Set of functional value. But generic equality
can't be used for functional values (raises an exception ...). It is
therefore difficult to build a Set of such values because the Set.Make
functor requires a comparison function and Pervasives.compare relies
on (=).
Is there a way around this ? I thought I could use physical equality
(wich is OK wrt functional values) but there's no such thing as
`physical inequality'.
