Probably yes. A possibility to use any type which has certain

Sorry, what is TIterator? Is this like to the previosly suggested
TIterator = interator(<Type>, MoveNext, Current)
end;
I did not try to specify what exactly TIterator is. What I tried to say
is: "some type that is already known at the point of parsing the for..in".
Btw, we can use some new 'enumerator'/'iterator' directive to mark
methods which return enumerators.
And only in delphi mode we will search for the GetEnumerator method.
The question is, what advantage all this specific syntax could give over
simple searching the methods by name?
