wow! That Plack advent calendar is brilliant. I am learning a lot from
it, however, I am not sure it helps me. Since I am already using
Dancer, I am "supposed" to be shielded from dealing with Plack
directly, no? In other words, (from the quote above), Dancer should
give me access to PATH_INFO and SCRIPT_NAME, etc. Which is precisely
what I want.
