Good question. The problem is that with

  include "somebig_chunk_of_code.f90"

one can include other code, which does not necessarily contain just PARAMETERs
(constants) and COMMONs but actual code. For instance octopus (tddft.org) does
this: It has a MODULE and includes one or two other files in it, which contain
subroutines/functions belonging to the  MODULE but are for maintenance reasons
in a separate file. (Fortran 2008's submodules would be a better replacement.)
