Huh? Are we talking about the same thing? Keyword arguments either overwrite
existing ones or supply new ones along with the call. What I am looking for is
more or less (and arguably sensible) syntactic sugar for building a subdict
of locals() given non-quoted variable names:

magic(a, b, ...) <-> {"a": locals("a"), "b": locals("b"), ...}

This is obviously not meaningful for expressions as arguments. I don't making
this look like a function call is a good thing, but I do think the functionality is
quite useful sometimes (Python, HTML, SQL, etc. generation...).
