Actually I am not sure what the OP *really* wanted either. :-)  I just
wanted to point out that the parameter is actually passed (which you
can see if you add a formal parameter to the block) but that the block
does not use it.

The index is only passed with #each_index.  And yes, of course it is a
parameter.

Kind regards
