Congrats on the fantastic hack that nobody else noticed! I've a feeling we cannot add tests for that, because any test would quickly break if we change the hash, though demonstrating that we fixed the problem would still be cool (eg. take two unsupported expressions of different kind but same type, and show that they're no longer reported).
One more minor comment.

I think `resize()` zero-initializes the whole new data(?)
