Why learn a whole new language for templating when you already know a perfectly good one? This isn't the first module that allows you to embed Perl in your templates, but it's yet another one.

use Types::Standard -types;
use Template::Compiled;

my $template = Template::Compiled->new(
  signature  => [
    name => Str,
    age  => Int->plus_coercions(Num, sub { int $_ } ),
  ],
  template   => '<p>Hi <?= $name ?>. You are <?= $age ?> years old.</p
+>',
  escape     => 'html',
);

# The number will be rounded.
# The ampersand will be escaped properly.
#
print $template->( name => 'Alice & Bob', age => 45.1 );
