I appreciate the elegance of Yehuda's proposal, but I think I have to 
agree with David Black's assessment that it is a solution looking for a 
problem.  It's not like its very hard to put the four letters 'proc' 
before the opening curly brace to disambiguate this case.

Also, it seems to me that a change of this magnitude should be targeted 
at Ruby 2.0, not dropped into a point release like 1.9.2!
