Re^2: Match range of number

Regexp::List should create a very efficient regex in this case.

use Regexp::List qw( );

my $rxValid = do {
   my $re_builder = Regexp::List->new();
   my $x_range = $re_builder->list2re(0..22);
   my $y_range = $re_builder->list2re(35..50);
   qr/ ^ X $x_range Y $y_range $/x;
};

I'd say Regexp::List is surprisingly fast: `perl bm.pl Rate rxValid plain Regexp::List rxValid 245760/s -- -19% -19% plain 303675/s 24% -- 0% Regexp::List 303675/s 24% 0% --` [download] Read more... (1238 Bytes) -- Andreas	[reply] [d/l] [select]
