There are a lot of expressions of the form constexpr.method(constexpr)
that could be safely evaluated at compile time and currently aren't.
It also occurred to me that if there were a set.frozen method
returning a frozenset, then (with compiler support) you could write
frozenset literals without new syntax.
And if dict.get and dict.__getitem__ (including the operator syntax
for the latter) made compile-time (frozen)dict literals the way "in
{...}" already makes frozenset literals, it would give you a
functional O(1) switch statement for some simple cases.
