Description
The node module yargs is callable (typeof require('yargs') === 'function'). It also has a property named default that is a function.
This makes writing a definition file very difficult. You'd be inclined to write
declare function yargs(): void;
declare namespace yargs {
/* dozens of other things */
function default(): void; // syntax error
}
export = yargs;There's not an obvious workaround that doesn't have bad side effects (e.g. rewriting the whole mess as a var doesn't really work in the case where there's a nested class), possibly requiring a massive restructuring of the entire file.
Wherever an identifier appears in an ambient context where it could have been initialized as a property, it should be allowed to be quoted. For example
export const "default": string;
declare namespace foo {
function "with"(): string;
}
