This lib I will certainly use whenever I come around and start on my own 
small meta
programming projects. One thing though; suppose I am developing lib B 
that uses
another lib A which already uses your MetaAssert, then I think that I 
would like to have
exceptions thrown only from my own library. That way, if I make a fault 
in my lib that
triggers a meta-assert in lib A I will know about it immediately (at 
compilation),
otherwise the exception might be mistaken as an expected exception from 
my own lib.

Would it be reasonable to add a tag or similar to each meta-assert so 
that the choice
between compile-time error and runtime exception can be made per library?
