I did an initial patch to add for..in iterator support in fcl-stl ghashmap (https://bugs.freepascal.org/view.php?id=35940)

I've looked at the docs of for..in, and it doesn't seem to name the delphi getenumerator() method in its options. I assume it is equal to point 5, the enumerator operator, because a for..in this way doesn't cause a memory leak.

"5. Any type for which an enumerator operator is defined. The enumerator operator must return a structured type that implements the IEnumerator interface. The type of the control variable’s type must equal the type of the enumerator’s GetCurrent return value type."

but maybe that could be said more explicitly?

What should be said more explicitly ?
