Nice.

In case you, or the reader, don't know: in handlers $_ is aliased to $_[1], so you can write ,$_->get_xpath(...) instead of $_[1]->get_xpath(...). Beyond saving 3 characters each time, I am used to $_ meaning "the current element" within a handler, and I find it easier to read.

a 'nice' from the module author... i'm honored... ;=)

I never noticed this feature of $_ set to $_[1] (or well, i used incosciously..)

May be worth to add some line in the Synopsis:

para    => sub { $_[1]->set_tag( 'p')  }, # change para to p (handlers
+ receive $twig and $element as argouments)
para    => sub { $_->set_tag( 'p')  },    # change para to p ($_ is al
+iased to $_[1] for convenience  )


###and in the corpus of the docs:

$_ is also set to the element (ie: $_[1]), so it is easy to write inli
+ne handlers like
