utils: imp module is removed in Python 3.12 - get is_frozen() from _imp
imp has been deprecated for a long time, and has finally been removed in Python
3.12 .
The successor importlib is using the same internal _imp module as imp, but
doesn't expose it's is_frozen. Using the internal function directly seems like
the cleanest solution.
Another alternative to
imp.is_frozen("__main__")
is
sys.modules['__main__'].__spec__.origin == 'frozen'
but that seems even more internal and fragile.
