Subject: [ruby-talk:30252] Bug in Enumerable#include? (Range#include?, actually) ???

I just observed the following behavioral differences between ruby 1.6.6 
and the latest 1.7.2:

ruby -ve 'puts ((1..5)).include?(0))'
ruby 1.7.2 (2001-12-31) [i686-linux]
-e:1: warning: puts (...) interpreted as grouped expression
true

ruby -ve 'puts ((1..5)).include?(0))'
ruby 1.6.6 (2001-12-26) [i686-linux]
-e:1: warning: puts (...) interpreted as grouped expression
false

It wasn't immediately obvious browsing CVS what caused this change, so 
I'll leave it to those who spend more time with the Ruby source.
