Here is an implementation for C++14 digit separators (single quote).


I tend to think that such features should come with a test that the
feature is not enabled for language / standard versions for which it
shouldn't be.  That is, something like

#define m(x) 0
int i = m(1'2)+(3'4);


Good idea.  Other than that, the patch looks good to me.
