Subject: Physical compare
Date: Wed, 23 Nov 2005 13:20:03 -0600 [thread overview]
Message-ID: <4384C0E3.5030300@confluent.org> (raw)
Is their a version of "compare" that is based on physical equality? If
not, how can I define one? I tried:
let compareq a b = if a == b then 0 else if a > b then 1 else (-1)
But unfortunately, (>) is a structural comparison.
I need to make a Map where the keys are distinguished by the physical
instance.
Thanks!
