This is similar to how we implement blocks in JRuby. All methods receive 
  a block, but it may be a "null block" that raises when yielded to and 
returns false for "given?". But there's always some kind of block 
regardless, and other than the syntactic sugar of yield versus call, 
it's largely the same code.
