One thing you want to watch with regex2...

regex2 => sub {
    my $tmp = $val;
    $val = join (" ",split " ",$val);
  },

... is if the variable has spaces contained in the phrase that you want to keep, this will get rid of them...

$var = "     Smart   Way      ";
$val = join (" ",split " ",$val);
print "var:  $var\n";  # $var now "Smart Way", internal spaces gone.

regex1 and regex2 would retain the internal spaces.
