I like this, the problem is, for this to be really useful we need:
if [ "$a" = "-s" ] ; then echo "hi" > = ; fi
if [ "$a" = "-s" ] ; then echo "yeh" ; fi
But the first if fails .... :-)
Joking aside, this may be correct, but it kind of fails the "gee whiz"
behaviour test. I suppose one would use a 'case' statement.
What is the "preferred" way of testing strings that may be arbitrarily
input then given the above ? I mean one does not know what 'a' is until
you do a test on it right ?

As I said I'll modify [ ... ] according to POSIX which will fix this
problem (maybe it was not clear that test and [ are the same). But in zsh
one can use
% a="-s"; if [[ "$a" = "-s" ]] then echo "yeh" ; fi
which should work with all zsh versions.
