To finish PEP 448, I need to update the grammar for syntax such as
{**x for x in it}
and
{1:2, 3:4, **a}
It's been a long time since I've looked at grammars and I could really use
the advice of an expert. I'm considering replacing:
dictorsetmaker: ( (test ':' test (comp_for | (',' test ':' test)* [','])) |
(test (comp_for | (',' test)* [','])) )
with:
dictpopulator: test ':' test | '**' test
dictorsetmaker: ( (dictpopulator (comp_for | (',' dictpopulator)* [','])) |
(test (comp_for | (',' test)* [','])) )
Am I headed in the right direction? Of course I will need to edit
parsermodule.c and ast.c.
Best,
Neil
