Just on a side note, would it not be better to use s/\s//g; or tr/\s//;.
I just did a benchmark on the two and the regex is approx 3 times quicker than the $_ = join ' ', split;
This is the benchmarik that I ran. 
use Benchmark;
my $junk = 'The quick brown fox Jumped over the lazy dog';
timethese(5000000,
{
    'split'    => '$junk = join \' \',split $junk;',
    'regex1'    => '$junk =~ tr/\s//;',
    'regex2'    => '$junk =~ s/\s//g;',
});

and the results are 
Benchmark: timing 5000000 iterations of regex1, regex2, split...
    regex1:  3 wallclock secs ( 4.38 usr +  0.00 sys =  4.38 CPU) @ 11
+42334.93/s (n=5000000)
    regex2:  3 wallclock secs ( 3.50 usr +  0.00 sys =  3.50 CPU) @ 14
+26940.64/s (n=5000000)
     split: 15 wallclock secs (15.07 usr +  0.00 sys = 15.07 CPU) @ 33
+1762.99/s (n=5000000)
