Not the same: in import statements it unambiguously replaces a list
of (optionally as-renamed) identifiers. Here, it would replace an
arbitrary expression, which I think would mean that we couldn't
differentiate between e.g.
with (expr).meth(): # a line break in "expr"
# would make the parens useful
and
with (expr1, expr2):
