A very frequent case is iterating over a list without using the integer index.
Would it make sense in this case to use the following form:

  for x in t do ...

  -- equivalent to current:   for _, x in ipairs(t) do ...

We could then use the numeric for for those cases where ipairs() and
the index are used today.

What do you think?
