I am not sure that the requirements are the same.  I thought they might
be similar, so threw the reference out there.  Take it FWIW.

No, you're not missing anything.  Both points about the syntax are
spot-on.

However, xParam's redirection operator '@' (from a file) provides an
alternative to multiple assignment.  Initially I was put off by this,
expecting that multiple assigment would be necessary or a just very 
convenient.  Neither turned out to be the case.  Now I'm getting along
easily without it.  I use xParam in an application which takes only the
most primitive parameters from the command line.  I haven't had to
resort to redirection.  Though I might, simply to make the (large)
parameter structures more readable.
