I have to warn here. This looks cool but it does something that AFAIK no other Python syntax uses -- it takes variable names and does something to those variables but *also* uses their actual names as string literals. I agree that the use cases for this seem pretty sweet, but perhaps we should give it a somewhat different syntax just so it's clear that the names on the LHS matter. The precedent that the targets must be actual names rather than anything you can assign to is also kind of scary. -- --Guido van Rossum (python.org/~guido)
