Subject: [ruby-talk:13357] passing blocks to Proc objects

Hello,

I am having trouble finding the syntax to pass a block of code to a Proc 
object.  I have some code which I am almost sure was working, but I recently 
noticed it didn't work.

This simple code illustrates my problem:

proc = Proc.new { yield }
proc.call { puts 'in block' }

gives me the error:

LocalJumpError: yield called out of block
(irb):1:in `irb_binding'
(irb):1:in `call'
(irb):2:in `irb_binding'
irb(main):003:0> 

----------------------
I can work around the problem by passing the code as an argument to the Proc 
object, but the block syntax really appeals to me.

Am I missing something here?

Thanks,
-Brad
