I vote against.

I accept that some ppl didn't remember in which sequence 10 and 13 was feeded to construct crlf and to some it was so hard to type the whole chr()+chr() thing.
so, it reasons somehow and @crlf was created.

@tab would be a macro of single character and would reduce the length of invoking it from 6 to 4 characters.
as a golf, that's a bad score.

anyways, I think not all want to know their ascii tables and thus I would not rip off my pants if this came to happen.
would just wonder a bit.
