// A type guard of the form x instanceof C, where C is of a subtype of the global type 'Function' 
// and C has a property named 'prototype'
//  - when true, narrows the type of x to the type of the 'prototype' property in C provided 
//    it is a subtype of the type of x, or
//  - when false, has no effect on the type of x.
