import React = require('react');
declare module BaseComponent {
var base : React.Component<any, {}>;
export = base;
}
class TestComponent extends React.Component<any, {}> {
render() {
return <BaseComponent />;
}

Environment:

- React 0.13.3
- DefinitelyTyped React definitions (DefinitelyTyped/DefinitelyTyped@71abea7)
- node v0.10.38
I discovered this issue while trying to write type definitions for the Griddle library. I'm new to TypeScript/TSX/React, so I apologize in advance if this is actually a problem with my code or with the React typings. The fact that the compiler crashed (and this is a new feature) suggested reporting here first.
