Now about that bug. What did you expect to see?
I expected tsc to compile the ambient types and test files successfully
What happened instead?
test/array-ext.ts:16:32 - error TS2345: Argument of type 'ComputedProperty<Fix<Person & { name: string; }> | undefined, Fix<Person & { name: string; }> | undefined>'is not assignable to parameter of type 'Person'.
Property 'name' is missing in type 'ComputedProperty<Fix<Person & { name: string; }> | undefined, Fix<Person & { name: string; }> | undefined>'.
16 assertType<Person | undefined>(array.get('firstObject'));NOTE
Switching to a TypeScript 2.x
npm install -g typescript@2
tsc
will compile the tests successfully and without error.
