You can have nested loops. Therefore, instead of "repeat/index"
you use "repeat/<loop-id>/index".

I remember that this is clearly specified in the specification.

When I remember right, the answer is "yes":

  They define two independent variables. The local one
  hides the global one inside its scope (provided the global
  one is defined outside this scope).
