"class" returns last value, and "def" returns nil in 1.8.

$ ruby -ve 'p(class X;true;end, def x;true;end)'
ruby 1.8.0 (2003-06-06) [i686-linux]
-e:1: warning: void value expression
-e:1: warning: void value expression
true
nil

# Hmmm, the warning for "class" doesn't seem appropriate.

If you mean Module#public, #private and so on, it should be a
Symbol for "def".
