I tend to agree, I think.

Belch. If we wanted the array-splice thing to resize arrays for us, then either we trigger the behavior only when rx/ \[ <scalar> \.\. <scalar> \]/, or we need to define the spilling algorithm in a way that makes sense (e.g. all remaining items go into the element of the righmost index). But perhaps there's a better way to beet the desire. Perhaps ellipses could be emplyed to indicate that the splice is allowed to resize the array: @a[1...3] = qw(a b c d e); Dave.
