Combine with Chet Ramey's reply, a strucure like below would work.
$ c=(a[0] a[1] a[2])
Careful. The elements are subject to filename expansion, so you need to
quote them to be safe.

ksh93 has a feature called nameref:
myfunc() {
nameref ref=$1
echo array $1 has ${#ref[*]} elements

I wouldn't mind seeing this in bash, though I'm not going to

IMHO it would be very desirable to have a indirect expansion facility
for arrays. Otherwise there is only a choice
with arrays:
$ a=(x y z)
$ b=a
$ echo ${!b[0]} ${!b[1]} ${!b[2]}

function, which

error-prone.
