[Python-Dev] Python Language Reference has no mention of list comÃprehensions

[Guido van Rossum]

I borrowed 'display' from the formal definition of ABC. It's still used in
the quick reference: http://homepages.cwi.nl/~steven/abc/qr.html#EXPRESSIONS
. I hadn't heard it before and didn't think to research its heritage. I
like it for list/set/dict displays since it's rather a stretch to call
those literals (they can contain expressions after all). I don't think of a
comprehension as a display though (even though it's syntactically related).
