This isn't a problem with nil.to_proc. You just have to know that nil is 
treated specially in the "&" syntax for method calls (it's equivalent to 
calling the method without a block, the to_proc method is *not* called). 
Which makes a lot of sense, by the way. Especially when passing around 
blocks.
