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.

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

1.8 is dead.
