iterator var over multiple cycles

[Wanradt Koell]

Hi!

I don't see, how to use iterator variable over multiple for-cycles? Is there some mechanism, how to use same sequence? I found such cumbersome way by nesting for-cycles, but it looks a bit ugly:

: for $items -> $item {

  <: $~item.count :> <: $item :>

:   if( $~item.is_last  ) {

:    for $set -> $id {

  <: $~item.count + $~id.count :> <: $id :>

:      if ( $~id.is_last ) {

:        for $stuff -> $thing {

  <: $~item.count + $~id.count + $~thing.count :> <: $thing :>

:        }

:      }

:     }

:   }

: }

I hope there is better way to achieve common sequence over multiple lists.

Wbr,
