The comma operator is an unintuitive operator with very few commendable uses.

If comma were added to the increment grammar of the for loop,
the comma operator could be removed from the language.

It's another piece of baggage from C.

About the only real use it gets in C is in preprocessor macro hacks. And we all know D's stance on preprocessing.

Or put to better purpose making (a,b,c) a literal tuple syntax. --

Just encountered another newbie reason for removing comma.

    writeln( 6, mixin("7,8"), 9 );

doesn't print the expected 6 7 8 9. Instead it prints 6 8 9.

If comma was removed, this wouldn't compile.
