When an interface file contains an error, it fails silently, resulting in unexpected errors:

declare module http {
  declare function createServer(callback?: (req: httpIncomingMessage, res: httpServerResponse) => void): httpServer

declare class httpServer {}
declare class httpIncomingMessage {}

// INVALID class method declaration syntax
declare class httpServerResponse {
  declare function end(chunk?: string): void

Results in:

Required module not found

@bhosmer took care of this in 729c2af. Now, your example results in:

flow-test/lib/test.js:10:11,18: Library parse error:
flow-test/lib/test.js:10:11,18: Unexpected identifier

which is much nicer!
