Can you explain when that creates a problem?
Maybe someone doing
for ([EMAIL PROTECTED])->$i { say @foo[$i] }
in stead of
say for @foo

I read ^5 as a range-list, like (in some mathematical notation) [0..5>
or [0..4].
Such a list can be stored as (start;count;step=1).
Yes, it could use a step:
^42.7 = (0, 7, 14, 21, 28, 35)
^42.-7 = (35, 28, 21, 14, 7, 0)
^-42.7 = (-35, -28, -21, -14, -7, 0)
^-42.-7 = (0, -7, -14, -21, -28, -35)
and (^-42.7 + ^42.7) has length 11, maybe better expressed as ^-42.7.42,
which makes '^5' the short way to write '^5.1.0'.
