Ah, I see: You have out-sourced the whole layout! Thank you for the hint, 
this idea has escaped me. This will help at least a little, but my hope 
was, that I could do such:

# input metacode_thistry
# input metacode_thattry
input metacode_perhapslikethis

and 

# input metacode_thistry
input metacode_thattry
# input metacode_perhapslikethis

…while mangling metapost code.

Best regards, Christian
