Potential CoffeeScript Bug

gistfile1.coffee

app.use thing.middleware
    src: __dirname
    compile: compile

#The above used to compile like this:
`app.use(thing.middleware({
  src: __dirname,
  compile: compile
}));`

#With the update to 1.5, you now get this:
`app.use(thing.middleware)({
  src: __dirname,
  compile: compile
});`

#WTF?
