Example Environment
- typescript@1.9.0-dev.20160207
- rxjs@5.0.0-beta.2
Abstraction
I found the case that the compile time of tsc increases to ~15x to resolve a complex function signature definition when I update rxjs to 5.0.0-beta.2 from 5.0.0-beta.1 (karen-irc/karen#574).
But after this commit, the compile time was recovered to the previous one.

rxjs@5.0.0-beta.2 has some pretty complex type signitured functions:
I know the type inference is not omnipotent, it need a complex computations, and this issue may be a corner-case of TypeScript compiler.
But I also think this would be a problem if libraries having a complex type signatures rises in the future.
Could you resolve this problem?
