Thanks for the advice but ...

Yes, in ASM a simple 25 or 33Mhz 386 computer was able to emulate
the
Spectrum. At least, under MSDOS, like did Warajevo, Z80, x128 and
"Spectrum"
from Pedro Gimeno.

In C99 you have "inline" (and gcc/gcc-llvm usually inline small
functions anyway) that helps avoid many macros.

Personally, I'd rather have Lisps lambda or perls sub then Cs
preprocessor, and even in those cases, Python suffices

Yes:
ReadMem = memory.__getitem__
