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'}"
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin10.8.0]
ok

system ~/projects/rubyspec $ rvm 1.9.2 do ruby -v -e "def foo; yield; 
end; method(:foo).to_proc.call {puts 'ok'}"
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin10.8.0]
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.

Issue #5926 has been updated by headius (Charles Nutter).


This should be fixed (if 1.8 is still open for fixes) or closed (if it 
is not).
