page doesn't work without todict

[christopher-dG]

https://github.com/JuliaWeb/Mux.jl/blob/master/src/routing.jl#L42

page(p::Vector, app...) = 
  branch(req -> length(p) == length(req[:path]) && matchpath!(p, req), app...)

req[:app] makes the assumption that the request is a Dict with that key, which is only the case when todict has been used.

I wonder if it might make sense to just make todict a built-in middleware, and if necessary just make the original Requst object a field in the resulting dictionary. @christopher-dG do you have a use-case that requires using the HTTP Request object directly?

[christopher-dG]

I was looking for the simplest path from an HTTP app to a Mux one, so I didn't want to change my handlers. I like working with structs over dicts, it's just preference really.

Given that pretty much all the provided middleware uses the assumed dictionary, it might be a decent chunk of work to add methods for using the Request object directly. There's also the question of, what do you use to pass state around between middleware. Any ideas?
