Bug #5926
closedProcs created by Method#to_proc do not pass block through.
Description
The Proc object you get back from a Method on which you have called to_proc does not appear to pass blocks through when called. I do not see any reason why it should behave this way.
system ~/projects/rubyspec $ rvm 1.8.7 do ruby -v -e "def foo; yield; end; method(:foo).to_proc.call {puts 'ok'}"
ruby 1.8.7 (2011-12-28 patchlevel 357) [i686-darwin10.8.0]
-e:1:in foo': no block given (LocalJumpError) from -e:1:in
to_proc'
from -e:1:in `call'
from -e:1
system ~/projects/rubyspec $ rvm 1.9.3 do ruby -v -e "def foo; yield; end; method(:foo).to_proc.call {puts 'ok'}"

Rubinius already implements it the 1.9 way in both 1.8 and 1.9 modes, and JRuby will do so from version 1.6.6 on.
