Clear? Really? To you and me maybe. Bash does so many crazy things
at the shell ... arithmetic, regexp substitution,
and tries to interpret so many characters as something,
I really don't want to go there.
I should be able to call up a file called $phones/at&t
without having to think about it.
And no idea what a mac or windows user would think of all that complexity.
What I have is generally liked, with no reported problems,
though there may be some hidden bugs and some concerns.
I like the idea of keeping my variable expansion,
perhaps augmented with ${var} or $(var) (makefile style),
and then call glob for the rest.
Glob is the hard part anyways, and the potentially unportable part,
so good to have a library do it.
This expansion can be suspended individually by ``
as in
r ``*
to read in the contents of a file called *
