I believe the latter is quite a bit *less* efficient. It has to
allocate a temporary list containing the numbers from 1 to $maxlen,
whereas the former does not. From perlop:
In the current implementation, no temporary array is created when
the range operator is used as the expression in "foreach" loops
With a small range it probably doesn't matter too much, but I find the
former expression far more self-documenting anyway.much.
