[Note, just to compare: in Lua, this little magic making builtin sequences

comprehension, bit with () instead of []. The semantic difference is that items
are generated once at a time instead of all in one go and stored in a list.
Another difference is that one cannot reuse such a generator object (once end is
reached, it is like empty).
