Comment 5 for bug 523899

A different example...

#{list items:0..5, as:'a'}
  ${a_index}
#{/list}

outputs: 1 2 3 4 5 6
(as expected)

However,

#{list items:0..5, as:'a'}
  ${a_index}
  #{list items:0..5, as:'b'}#{/list}
#{/list}

outputs:
1 8 8 8 8 8

The mere presence of a nested list breaks a_index.
