I think yes!

But maybe "set" is enough? Didn't play with it much.

e.g.:

- available Mapsets: A, B , C, D, E1, E2, E3, E4
- accessible Mapsets: A, B, E1, E4
- the task is to loop over all E?s (that is, E1, E2, E3, E4) and do something

so:

- inside A
- launch loop
- enter in E1, remove all but E1 from being accessible, do something
- enter in E2 and, keep access only to E2, do something
- and so on...

thnx, Nikos
