Isn't this similar in a way to C/C++ with their header files all
over the place? Also in modern Fortran, each module Fortran .f file will
have an associated .mod file generated that goes with it (used by
other modules to interface to it).

I think having the implementation in one file and the interface in
separate file is good.

Otherwise, if they are both in same physical file and one changes
say the implementation only, causing the time stamp on the file to
change, then hard to know later if one changed the implementation part
or the interface part in the file by looking at timestamps of
files that changed (make will not know also, so it thinks both changed).

Also having separate file for interface and implementation,
allows others to program against the interface file, while someone at same
time changing the implementation file without each getting in each others way.
