It seems that indirect expansion doesn't work with arrays:

Is that intended? The documentation isn't explicit about it.
IMHO it would be very desirable to have a indirect expansion facility
for arrays. Otherwise there is only a choice between passing all
elements to a function, which is time-consuming, or using eval, which is
cumbersome and error-prone.
yes, that would be nice - as a feature.
but it somehow conflicts logically with ${!arr...@]}, which returns the
indicies of an array (some ksh derivied feature I think).
