Please forgive me. I may have missed some mail that went by in the 
past, but I still don't understand:

& ruby16 -ve 'def foo(a=5); end; p foo()'
ruby 1.6.8 (2002-12-24) [powerpc-darwin7.0]
nil

& ruby -ve 'def foo(a=5); end; p foo()'
ruby 1.8.2 (2004-12-25) [i386-freebsd4]
nil

& ruby -ve 'def foo(a=5); end; p foo()'
ruby 1.8.2 (2004-12-20) [powerpc-darwin7.7.0]
nil

To make sure, I checked the change logs between 11/15 and 11/29 (when 
the commit was made) to make sure I didn't skip over something 
relevant. I might have missed something though. Again, sorry for the 
trouble, I'm just trying to understand if I can tighten down our 
assertions on one of our projects.
