see if we can get rid of any dependencies

like 04-crosscontroller does.

like the test one, that setups up a plack::request and response

test with test plack?

need a default handler, and it needs to work across frontends.

perhaps we can use the Return::MultiLevel return thing from #19

would they be the things Getopt::Long would normally collect?

can it be made to have some validation? and handle flags correctly

e.g. -n vs --file foo --path=/tmp

use Return::MultiLevel and setup a generic mechinism like cat does for forward/go/visit/detach, but cat uses die.

can we localize that the same as we do for the request/response?

That sets up the test req/res and so on

wrap dispatch in a try {} catch {} and do somekind of error handling

to check that the dispatcher builds a string to match, instead of a regex
