Macros: why and/or when to use them?

[kcvinu]

I know that the people behind Nim doesn't like when I said, "Hey there is a 
problem in modularity". So I stated it in good words. If I say, it's my 
problem, they will say, "Okay then learn how to solve it." But I know that I 
don't have any problem in modularity in other languages. I know they are 
working hard to improve Nim but there are still some problems. And for me, 
there is a language barrier to express my thoughts in this forum. So please do 
not get me wrong.
