Hi monks!

Is it possible to use perl subroutines inside regexp, using backreferences as parameters? Something like this 

sub test{
  my $value=shift;
  print $value;
  return 'la-la-la' ;
}

my $str = 'Hello _world_';

$str =~ s/_(.*?)_/&test(\1)/g;

I want to get 'Hello la-la-la' in $str, by get Hello &test(world).

May be I've got XY problem? I want to use in templates in my web-framework something like 

....
 <body>
  ... {_SomeModule_}
 </body>
...

So, the output of SomeModule should be substituted in template. So, if I want to write something like s/{_(.*?)_}/&call_module(\1)/g

Thanks, Alex.
