Forgot about leading whitespace...
Assuming we don't do that... there really is no diff.
Thanx for clearing that up, but I still think it's confusing.
From the perlfunc pages:
As a special case, specifying a PATTERN of space (' ') will split on
white space just as split with no arguments does. Thus, split(' ') can
be used to emulate awk's default behavior, whereas split(/ /)
will give you as many null initial fields as there are leading spaces.
A split on /\s+/ is like a split(' ') except that any leading
whitespace produces a null first field. A split with no arguments
really does a split(' ', $_) internally.
