I was going to assert that this would generally be equivalent to splitting on whitespace, with the obvious difference that, if the string began with whitespace, split would return a list that included an empty string as the first element -- the first element returned by the regex would be the second element returned by split.

You obviously didn't test it :-) split ' ' (as posted) is MAGICAL. It is not the same as split /\s*/. 

@v = split ' ', '    watch the magic    ';
print "$_: $v[$_]\n" for 0..$#v;

print $/;

@v = split /\s+/, '    lost the magic    ';
print "$_: $v[$_]\n" for 0..$#v;
__DATA__
0: watch
1: the
2: magic

0: 
1: lost
2: the
3: magic

As you see it is absolutely identical to the posted RE and drops leading whitespace.
