in thread remove both leading and trailing spaces

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.
