local variables, 200 I think, the number must fit into one byte
otherwise the whole VM needs to be redesigned. Whereas
the number of global variables is for all practical purposes
unlimited.
IIRC, local variables are implemented over VM registers (similar to how a native language uses CPU registers and/or the stack), so the limit would be per-function. Not a problem normally, that is.
