support variadic usage (rather than requiring an array)

this is just my ocd, but imo the latter looks much nicer:

app.use(route.get('/foo', compose([ middleware1, middleware2, routeHandler ])))

vs

app.use(route.get('/foo', compose(middleware1, middleware2, routeHandler)))

would you take a pr implementing this in a backward compatible way?

i would personally like:

function compose(...args) {
  const middleware = _.flatten(args)
  // ...
}

@tj @juliangruber @dead-horse @fengmk2 thoughts?

I forgot the PR that added this got reverted and wasted a bunch of time debugging… any chance we’d be up for trying this again?

Also, any news on “the use-case for mutating middleware”?
