Ah, now I understand your question, sorry for being dense before.

Through a bit of hackery, Meroon macros are available whether loaded or 
included.  See meroon.gsc for the gory details.  (Basically, each 
meroon-macro definition in a file A.scm  [which is available to use in 
other definitions in A.scm] is also "eval"-ed, which makes it available 
to  use in definitions in other files after A.scm or A.o1 is 
"load"-ed.)

I would recommend you just "include" or "load" each file with Meroon 
class/generic/method definitions once.
