[Catalyst] Subsessions?

[Yuval Kogman]

A somewhat naive idea:

sub session {
	my $c = shift;

	if ( my $sub = $self->subsession_id ) {
		return $self->NEXT::session->{$sub} ||= {};
	} else {
		$self->NEXT::session(@_);
	}
}

subsession_id can be some param I suppose like in State::URI. You
can probably subclass State::URI to make it so that it doesn't plug
into the session system, but instead goes to subsession_id, or just
keep track of it manually.

Cheers,
