[TxMt] Converting a single-line block into a multi-line block

[David Lee]

just to complicate matters, I much prefer the curlybrace style  
expansion. It's also more robust:

items.collect { |i| i.children  }.reject{|c| c.children.empty? }

with your regex macro becomes

items.collect do |i|
   i.children
end.reject{|c| c.children.empty? }

which is illegal Ruby; with a curly-style expansion your macro holds  
up admirably.

I know it's easy enough to change manually, but if your'e considering  
putting it in the distribution I'd advise to err on the side of curlies

( hope I'm not starting a ruby style religious war ... )

cheers,
David
