export const y = 0;
// no error, works as expected
export type Ident = <T>(x: T) => T;
// no error, works as expected
export interface Obj {
add: (x: number, y: number) => number;
}
export const someFunc: {
// error 'x' is already declared in the upper scope
// error not expected
<T>(x: T): T;
// error 'x' is already declared in the upper scope
// error 'y' is already declared in the upper scope
// error not expected
<T>(x: T, y: number): T | number;
} = (a, b?: number) => b ?? a;
export interface IFunc {
