It's probably what you're trying to avoid, but you'll probably have to
construct and then eval the right code by hand:
$(eval "echo \${#$name[*]}")
bingo. (sigh)
I refactored and am essentially using spaces to store the values in
a string, then when I want to check the, I throw them into an array and
manip.
e.g. (not showing all supporting code)
declare -axr _plst_t='_plist_'
declare -axl defined_PLists=()
add things to the list...
plist="$_plst_t$plist"
local -al plist_deps=( $plist )
{search for value in list, ...]
unless ((found)) ; then
plist_deps[${#plist_deps[*]}]="$subdep"
eval "$plist=( "$plist_deps[@]" )"
fi
