[texhax] le vs leq and \ZZ vs \Z

Dear list,

1. I'm using LaTeX for quite some time now and have always wondered why
there are two possibilities to typeset the "less or equal than" symbol.

Why are there two commands "le" and "leq" to typeset the same symbol?
Is it just for historical reasons or is there a "proper" way to do it?

2. Along the lines of "doing things properly":  There are certainly lots
of people out there who use on of the two following macros


to typeset integers.  While the second one is shorter, a friend of mine
warned by about one-letter-macros labelling them "bad style".  Do you agree?

Kind regards,
