PREFIX is optional in Dispatch. What is the harm in this?
TABLE => [
'blog/:rm' => { app => 'MySite::Blog' },
'admin/:app/:rm' => { app => 'MySite::Admin' }
'get/:path' => { app => 'MySite::GetDoc' }
':app/:rm' => { }
]

I had to read your example three times before I understood why which
is what I'm getting at. This still seems too confusing. It seems to me
there has to be a better way or perhaps, in order to support what you
propose, some form of simple regex pattern matching is required to
disambiguate URL patterns like in your first example. This way :year
can be defined as 4 digits (\d{4}) and will let single parameters fall
to another rule. Rails has such a feature in their routes. That left
side could get really gruesome looking if your patterns are complex
enough.
