changing terminology (was: overview paper co-author invitation)

so make iter[] an operator like i said. how are we gonna pronounce it anyway.

That does not solve the problem of wording.
And btw. there is no iter operator because there are different methods to define extended iteration (thats the board about! )

Extended iteration is not an operator but a property, something is an iterational of something else, if it satisfies blabla. There can be several iterationals for one something else.

Only integer iteration is an operator.
