	ah yes, the revenge of the glaringly obvious typo.

	my next question, then, is why the following occurs:

(astaroth)~1: joe='hello world'
(astaroth)~2: bob=joe
(astaroth)~3: echo ${joe}
hello world
(astaroth)~4: echo ${bob}
joe
(astaroth)~5: echo ${${bob}}
joe
(astaroth)~6: echo ${(e)bob}
joe
(astaroth)~7: echo "echo \${$(echo ${bob})}"
echo ${joe}
(astaroth)~8: `echo "echo \${$(echo ${bob})}"`
joe
(astaroth)~9: echo ${ZSH_VERSION}
3.1.5

	i would think that #5 should print hello world,
that #6 would explicitly cause parameter expansion and
print hello world, and that #8 would evaluate the results
of #7, which would be the same as typing #3, and would
thus print hello world.
