Minor update: I think that YAML syntax for these kinds of routes is a
little bit verbose; any thoughts on this syntax:
/                    Home       GET
/user/#userid        User       GET PUT DELETE
/static              Static     StaticRoutes staticRoutes
/foo/*slurp          Foo
/bar/$barparam       Bar
First column is the pattern, second is the constructor name, and after
that you have three possibilities:
Nothing is a handler function for any request method. Above, the fourth
and fifth entries.
A list of request methods will allow a handler function for each request
method. Above, the first and second entries.
A datatype and function name, allowing a subsite datatype and subsite
function. Above,the third entry. I'll need to develop this one a bit more.
How would this pattern be translated to the new scheme ?
/entries/$entryId/$filename:
    GET: media
I am guessing:
/entries/$entryId/$filename    Media    GET
And the Media constructor would be:
| Media String String
?
- jeremy
/entries/$entryId/$filename:
Exactly, with the dispatch function being:

getMedia :: String -> String -> Application

(Actually, there's most likely going to be some type of argument datatype as
well, which is where the complication I alluded to with subsites comes from.
However, I'll address this more clearly when there's some actual code to
back it up.)
