sub lang :Chained('/') :CaptureArgs(1) :PathPart('') {
   my ($self, $c, $lang) = @_;
   <set lang appropriately>
}

sub foo :Chained('/lang') :Args(0) { # /en/foo etc.

Chained was designed to support this sort of stuff without the need for 
prepare_path hacks, which I've used before but always found a tad ugly.
