So for the last few day's I've been mucking around with mojolicious, and there is a lot I like about it, and well a lot I don't... primarily in that it allows for some rather spaghetti mess looking templating. (like PHP)

So I just wrote this silly little thing I call Slang!

It's pretty fast too... (I think)

#!/usr/bin/perl
use Modern::Perl;
use Slang qw ( mask );
use Bench;

Bench::Start();

local $_;

$_->{'mask'} = join ('', <DATA> );

$_->{'stash'} = {   lang => "en",
                   title => { en => "Bob's Bit's Emporium" },
                 content => { en => "<s>greetings.<s>lang</></>" },
               greetings => { en => "Welcome!" }
               };

say mask($_->{'mask'},$_->{'stash'});

Bench::MileStone();

say mask($_->{'mask'},$_->{'stash'});
say mask($_->{'mask'},$_->{'stash'});
say mask($_->{'mask'},$_->{'stash'});
say mask($_->{'mask'},$_->{'stash'});
say mask($_->{'mask'},$_->{'stash'});


Bench::End();
Bench::Report();


__DATA__
<html lang="<s>lang</>">
  <head><title><s>title.<s>lang</></></title></head>
  <body><s>content.<s>lang</></></body>
</html>
