"export default interface" does not compile

[nippur72]

This works

interface A {
   a: string;
} 
export default A;

but this does not:

export default interface A {
   a: string;
} 

error TS1005: ';' expected.

Tooltip over the keyword interface:

The name 'interface' cannot be found.

You should really search for issues before opening a new one.
