Re: path PATH

It's actually the other way around; it's special (because it cannot be

It's the only one that displays as 'export -T'.  Here, anyway.

These scalar variables are tied, exported,
and special:

PATH
MANPATH

Here: MANPATH is: 'typeset -T' like several others.  But it's good to 
know that indeed there are special values that will be treated 
differently.  So I was right about PATH but for the wrong reason ... 
which is simply being wrong.

The
reason for this tied behavior is so that the scalar parts CAN be
exported, because the environment cannot contain arrays.

Ah!  That answers my question as to what all this tie-dying is about.  I 
had no idea you can't export arrays.  Marvelous.  You know, when you 
understand why something is, then what it is becomes much easier.  The 
clouds part.
