the new features, but instead provides a convenient overview of the
new features. For full details, you should refer to 2.2 documentation

do support random access. The basic idea of iterators is quite
simple. A new built-in function, \function{iter(obj)}, returns an
iterator for the object \var{obj}. (It can also take two arguments:
\code{iter(\var{C}, \var{sentinel})} will call the callable \var{C}, until it
returns \var{sentinel}, which will signal that the iterator is done. This form probably won't be used very often.)

This shouldn't be much of a limitation, since \keyword{exec} is rarely
