Subject: Re: yield/block propagation

I might miss what you are wanting to do... but are you looking for the
"&" trick for collecting the block, so you can pass it on?

[ensemble] ~/p/ruby/vcard $ irb
irb(main):001:0> def foo; yield "hello, world"; end
nil
irb(main):002:0> def bar(&proc); puts '"'; foo &proc; puts '"'; end
nil
irb(main):003:0> bar { |h| puts "#{h} #{h}" }
"
hello, world hello, world
"
nil

Cheers,
Sam
