While that might make for nice default breadcrumbs, it wouldn't be expressive enough for all use cases. I think we should reserve indentation to indicate route nesting:

/posts PostsR
    /#Int PostR
        /comments CommentR

There seems to be much redundant information created within the Yesod structure.
One place to define the routes
Another place defines the route hierarchy for breadcrumbs with titles.
A third place defines, but not integrated into Yesod, defines use menus (usually similar hierarchy and titles).

Would it be possible to have all of this defined into one place, by extending the routes definition using white space
hierarchy similar to hamlet definition.
and optionally include Title name.

-- Example config/routes
/static StaticR Static getStatic
/favicon.ico FaviconR GET
/robots.txt RobotsR GET
/ RootR GET "Home"
   /contact  ContactR GET  "Contact Us"
   /services ServicesR GET  "Our Services"
       /services/stuffwedo StuffWeDoR GET "Stuff We Do"

The resource list would be expanded to include this hierarchy. Something like
Resource String <http://hackage.haskell.org/packages/archive/base/4.3.1.0/doc/html/Data-Char.html#t:String> [Piece <http://hackage.haskell.org/packages/archive/web-routes-quasi/0.6.3/doc/html/Web-Routes-Quasi-Parse.html#t:Piece>] [String <http://hackage.haskell.org/packages/archive/base/4.3.1.0/doc/html/Data-Char.html#t:String>]  String Maybe String

>From this a breadcrumb could be build from a maker (if desired).

mkYesodData "Example" $(parseRoutesFile "config/routes")
mkYesodBreadcrumbs "Example" resourcesExample -- creates breadcrumbsExample


and a hierarchy useful for building Menus

mkYesodHierarchy "Example" resourcesExample -- creates a nested table of (Route, Html) pairs

The menu list could also be pulled from the data, with possible few options.
