@tk0miya -- should line 186 also be updated for ~typing.Literal? I haven't debugged locally, but it is the only other occurance of the string typing.Literal in the module.

No, you don't need it. In AST level, the ~ prefix is separated to an independent node ast.Invert. So it will never take ~typing.Literal value.
