Arrays

Pike v8.0 release 702 running Hilfe v3.5 (Incremental Pike Frontend)

> array(string) flat = ({"this", "that", "the", "other"});
> flat[1];(4) Result: "that"

> flat[1]=3;
(5) Result: 3

> flat[1];
(6) Result: 3

I was under the impression that array(string) would exclude any
other data types but strings.

What's going on?
