I like that, it is similar to a proposal for docstrings:

https://bugs.python.org/issue36906

This would be safe to optimize at compile time, so long as the contents
of the set were all literals. And for implementations that didn't
optimize at compile time, it would be no worse than the situation now.

Perhaps a better name would be "frozen()` since that doesn't imply
an in-place operation like "freeze" does.
