Well, sure, if you split() on \S.
@ws = split /\S/, $string;
But we're not split()ing. We're matching all non-spaces.
my @non_ws = $string =~ /(\S)/g;
Or, since a global pattern match in list context without ()'s will return
the entire match:
my @non_ws = $string =~ /\S/g;
This will be an example in my book.
