Circular import on fparser 0.2.3

[tbennun]

Importing a package with the newly-released fparser triggers an import error:

>>> from fparser.two import Fortran2008
E   ImportError: cannot import name 'Loop_Control' from partially initialized module 'fparser.two.Fortran2008' (most likely due to a circular import) (/opt/hostedtoolcache/Python/3.13.13/x64/lib/python3.13/site-packages/fparser/two/Fortran2008/__init__.py)

Ah! That's unfortunate - thanks for reporting. I note that if you do from fparser.two import Fortran2003 first then Fortran2008 can subsequently be imported. I'll take a look.

Note that running pytest test_label_do_stmt_r816.py in isolation reproduces this problem. I need to work out how to test in in a normal run of the test suite.

I took a leaf out of Martin's book and used Claude to tell me how to write a test. It was actually pretty simple in the end (use subprocess to start a brand-new interpreter).
