Solution without eval:

    addtoarray() { [[ -d $1 ]] && set -A $2 $1 ${(P)2}  }

Various quoting may be necessary if you using an emulation mode or
other nonstandard setopts, but from your original example it does
not appear so.  ${(P)2} means to treat the value of $2 as a name
and expand that named parameter.
