That is so, but none of what is discussed is compatible with Delphi, 
since Delphi uses hardcoded names, so in Delphi mode you'll have to 
add some separate checks anyway.

In objfpc code, the single call could be enough.

In each case, you'll always need 2 calls: 1 call in class itself to
Create Iterator instance, and the iterator call in the iterator instance.

I suggest you think about it when writing the specs, then we can discuss
further...
