TypeScript Version: 2.0.10 (broken since 2.0.2).

Code

exporttypeFoo<A,B>=A|B;exporttypeBar<T>=Foo<number,T>;exportconstf=<T>(bar: Bar<T>)=>{returntrue;};

Expected behavior:
tsc --declaration bar.ts should emit the following bar.d.ts:

exportdeclaretypeFoo<A,B>=A|B;exportdeclaretypeBar<T>=Foo<number,T>;exportdeclareconstf: <T>(bar: Bar<T>)=>boolean;

NB: 2.0.0 emits <T>(bar: number | T) => boolean, which is acceptable too.

Actual behavior:

exportdeclaretypeFoo<A,B>=A|B;exportdeclaretypeBar<T>=Foo<number,T>;exportdeclareconstf: <T>(bar: Foo<T>)=>boolean;// TS2314: Generic type 'Foo' requires 2 type argument(s).

                          TypeScript Version: 2.0.10 (broken since 2.0.2).
                          Code
                          exporttypeFoo<A,B>=A|B;exporttypeBar<T>=Foo<number,T>;exportconstf=<T>(bar: Bar<T>)=>{returntrue;};
                          Expected behavior:
                          tsc --declaration bar.ts should emit the following bar.d.ts:
                          exportdeclaretypeFoo<A,B>=A|B;exportdeclaretypeBar<T>=Foo<number,T>;exportdeclareconstf: <T>(bar: Bar<T>)=>boolean;
                          NB: 2.0.0 emits <T>(bar: number | T) => boolean, which is acceptable too.
                          Actual behavior:
                          exportdeclaretypeFoo<A,B>=A|B;exportdeclaretypeBar<T>=Foo<number,T>;exportdeclareconstf: <T>(bar: Foo<T>)=>boolean;// TS2314: Generic type 'Foo' requires 2 type argument(s).
