Notice also that commands and environments in LaTeX are not
interchangeable; there are things only commands can do and things only
environments can do.  (Well, not really - technically, I guess,
environments are strictly more powerful than commands, though I'm not
100% sure - but some things are quite difficult to do with environments
and trivial with commands.)
