I didn't realize the handin server used it when I removed it. It definitely doesn't need it.
The #:namespace argument made it so the closure given as the request handler was called in a different namespace than it was evaluated in, causing a reinstantiation of the module and other weirdness. For example, #lang web-server/insta (require (only-in "some-stateful-module.rkt" set-a! unbox-a)) ; where a defaults to "Hello World" (set-a! "Hello World, not") (define (start req) (unbox-a)) would evaluate to "Hello World" instead of "Hello World, not", because some-stateful-module was not shared with the new namespace. This seems incredibly wrong, so I removed the namespace argument and the request handler closure is simply evaluated in the namespace it came from. The #:namespace argument is still useful for other servlets that come from serve/servlet, because they are loaded from disk and may need to share some modules with the main one, but should otherwise be isolated.
