What about just not using comma operator? Yes, I know about keyboard 
issue. There are many cases when 'typoed' code compiles but doesn't work 
as programmer would expect. This is not limited to comma op.

Some programmers do not like gotos, comma operator or other language 
constructs. Some like the opposites. I would suggest making a patch to 
the compiler to introduce a new pragma:

pragma(disable, commaOp);

and programmers will be able to place it in every source file they want to.
