For what it's worth, I've addressed the situation by:
1) declaring subwords in 'macro'
2) factoring out as much from the subwords as possible,
    putting it into as few non-macro words as possible
This allows me to reference a macro subword just like it's an actual 
subroutine, and for each reference to generate the minimum possible 
amount of code.
