Re^2: Efficient but elegant Cross-Product iterator ?

Thanks, pretty close but not exactly what I'm trying to achieve in the end.

Some interesting ideas though.

The code looks like written by an experienced C programmer.° ;)

One point with "when" looks buggy, will need to install and test.

Didn't know it's possible to use isa instead of ref to test for a CODE ref (?) Strange!
