This won't compile: Obviously the "nop" is just a place holder for any useful macro, this is only an example. I know I can use REPT but I want the value "4" above to actually be a variable that depends on other code for it's value. Is there a trick to make this work or is this a bug?

"repeat" was implemented exactly for this reason.

Oops, yeah, I forgot to mention that my current solution is using REPEAT. But it was just that TIMES looked nicer in the code. Anyhow it is not an important problem, just something I noticed.

I didn't see it as a problem when I was implementing it this way - the "times" is the just like any other assembler's directive or instruction, thus macros are not recognized inside it's arguments (you cannot do "rep foo", too) .
