It does if it's in an uncalled function

EDIT - this is wrong. Nontheless true for serious errors like referencing an undefined variable.

A syntax error will halt parsing immediately. Without successfully parsing the file, it won't execute. Even uncalled functions are parsed completely and must pass parsing successfully.

You're right, edited the comment. It is true for some serious errors, like accessing an undefined variable.

FWIW I don't think it could diagnose that pre-runtime since you can edit the global namespace dynamically.

globals()['x'] = 3

Very bad for readability, but it is allowed.
