I can't remember if we've discussed this idea before, but a simple way 
to handle in the future might be simply to introduce a syntax for 
referring to specific locals - function:::local, file:line:::local, for 
instance.  You get a sal that maps to a block, then can find the block's 
symbol with that name.  If the name also occurs in superblocks, you 
could make a policy decision as to whether to include the first found, 
or all found.
