Ask HN: TypeScript experts, is this a type checking issue?

The following ts code both compiles (with all checks active) and passes tslint without complaints: type sig = (p: number) => string; const x = (p: any) => p + 1; const y: sig = x; alert(typeof y(5)); Obviously the alert message will (and does) display 'number'. IntelliJ spots the problem though ('x' should probably not be assigned to 'y'). (Apologies if this is too stackoverflow-y, but I don't expect a "solution", I'm just interested in opinions)
