The only way I know to make this work is to use parsetree or nodewrap to 
build a custom parser for the block.  I've tinkered with doing this, but 
it always turns out too hard for the user (actually, everything's easy 
except for how Ruby handles local variables -- I think need to build an 
intermediate representation for the Ruby code that can be easily 
transformed).

The solution you came up with is probably cleaner, at least for the time 
being.
