Quoting from the docs,
Raised when a built-in operation or function is applied to an object of
inappropriate type. The associated value is a string giving details about
the type mismatch.
In addition to your comments, this is not a built-in operation, so it's
the wrong exception.

Raised when a built-in operation or function receives an argument that
has the right type but an inappropriate value, and the situation is not
described by a more precise exception such as IndexError.
Yup, seems reasonable. I'll change. Thanks!
See you at the next Calvinball tournament, Spaceman Lee.
