Before your code is executed, python scans your entire file for syntax
errors. Since 123.45_f is currently not a valid literal, it'll just
print a syntax error without even looking at your imports.

To change that, the very core of python would need to look completely
different. It'd be a metric fuckton of work for a whole lot of people.
Im not a core dev myself or anything, but i'm pretty confident that
this isn't going to happen for a rather minor need like this.
