Allow export default interface

[LPGhatguy]

The following snippet is valid, as far as I know:

export interface User {
    wpUserID: string;
}

The following snippet is also valid, but does not compile, but probably should:

export default interface User {
    wpUserID: string;
}

I get errors thrown at me when using TypeScript 1.5-beta:

Error: /Models/User.ts(1,26): Error TS1005: ';' expected.
Error: /Models/User.ts(1,31): Error TS1005: ';' expected.

You can get around this with

interface I {

}

export default I;

I admit this is a somewhat strange inconsistency, but this is a duplicate of #3194 and is by design in accordance with a decision made on #3095 (comment).

Interesting. Any chance there could be a warning about the behavior?

Linking to #3792 because they're very similar. We should just allow this kind of thing. There's no good reason to require you to write it in 2 statements instead of one.

👍

Currently I am doing the "workaround" with everything for consistency, would be nice to switch though.

👍 Any kind of error would be welcome, it took a StackOverflow question to understand.

closing in favor of #3792
