Is this supposed to be Haskell code or Haskell semantics?

For me it looks more like LISP phrased in Perl..

Did you mean:

sub all_even_from{ my $even=shift; sub { $even+=2; } } $iter=all_even_from(4); print $iter->() for (1..5);
?

I didn't talk about operators but about tie.

Using Tie::Array you could try to tie the iterator to an array @even such that you can subsequently write something like this, _with_ lazy evaluation.

for (1 ..5) { print shift @even; }

again, show me what you like about Haskell - eg list comprehensions (???) - and I will see whats feasible.

Cheers Rolf
