No.  That's even worse.  If you don't like the comma separation,we
could as well accept multiple -n args:

env import -n name [-n name1 ... ] [other_flags] addr [size]

What does -a stand for?  "all" ?

Should be no problem in general, except for the pathological cases
like variable names "-f" etc.   But there has to be a penalty for such
stupid names :-)
