Description
Describe the issue:
Take this F90 module:
MODULE F_GLOBALS
IMPLICIT NONE
INTEGER, PARAMETER :: N_MAX = 16
INTEGER, PARAMETER :: I_MAX = 18
INTEGER, PARAMETER :: J_MAX = 72
...
END MODULE F_GLOBALS
When compiled with f2py 2.0.1 and included as "f_test" in a Python script, this:
import f_test as f
maxN = f.f_globals.n_max
maxI = f.f_globals.i_max
maxJ = f.f_globals.j_max
will cause this error message:
AttributeError: module 'f_test' has no attribute 'f_globals'
Reproduce the code example:
> f2py -c -m f_test F_GLOBALS.f90
import f_test as f
maxN = f.f_globals.n_max
maxI = f.f_globals.i_max
maxJ = f.f_globals.j_maxError message:

Context for the issue:
Code which ran fine in numpy 1.26 fails to run in numpy 2.0.1.
A simple if ugly workaround is to add some executable code within the module. Only then will it become visible in Python, including all the assigned variables..
