No. IEEE 1800-2012 § 7.8.1 Wildcard index type states:

Associative arrays that specify a wildcard index type shall not be used in a foreach loop (see 12.7.3) or with an array manipulation method (see 7.12) that returns an index value or array of values.

The reason for this restriction is that the foreach construct needs to declare a local iterator variable, and that variable needs a type. The wildcard index is left over from the Vera language, which did not have the ability to declare an index type. Do not use wildcard indexes.
