	.... Earth to Peter ... Earth to Peter ...   8^)

	First, I create an alias:
alias test='$(which ls)'

	Let's see!!!  I type "alias (set -a)" (quotes not included) and I get
.
.
.
test		= $(which ls)
.
.
.
	(No variable expansion, as was expected).

	Now, if I type "which ls" (again, quotes not included), I get
sys:bin/ls
	[ sys:bin is where I keep "ls" ]

	If I type "$(which ls) -a", I get a Usage message from the "ls"
	command under sys:bin.  With me so far???!!

	Now I type "test -a".  I got the same Usage message!!!

	What could all this mean?  That Steve Koren knows his stuff!!!  8^)

	Good job Steve!!!!!!!!
