good thought, yes.  (and your hunch that the problem lies in the .inc was spot
on too)  I'm not yet quite sure how, but the code needs to be .. re-structured.
one/the concern is the size of the .inc file; ironically,  the "troublesome"
'fore_call()' was written to reduce duplication of code within the "walkers".
