It can be indeed handy. What I don't like about the Intel option is that
it not only creates a .mod file but also a .f90 file with the module
information. That option is nice, but if one only wants to do error
checking, cluttering the directory with .f90 files is not what one wants.

I thought I filled a bug, but I cannot find it anymore ... ok, I think,
I only wrote it in an email.
I now filled a bug:

Well, I have also seen several Fortran 90 codes which use one file per
procedure and and use "external" without creating a module.

Well, you could start with something smaller in gfortran ;-)
