💻 Code

    method(x:number): string;
    method(x:string): number;
    method(x:string | number): string | number {
        if (typeof x === 'string') return 0;
        return '';
    }
    method1: () => string;
    method2: () => number;

    constructor() {
        this.method1 = this.method.bind(this, 0);
        this.method2 = this.method.bind(this, '');
    }
}

🙁 Actual behavior

in method1's definition, typescript only reads one of the two method signatures (the first one) when you use bind on it.

🙂 Expected behavior

TypeScript should read all the available signatures when you call the bind method on your method. Because that's the purpose of method overloads.
