Usage

function foo() {}
foo.unicorn = '🦄';
function wrapper() {
return foo();
}
console.log(wrapper.name);
//=> 'wrapper'
mimicFunction(wrapper, foo);
console.log(wrapper.name);
//=> 'foo'
console.log(wrapper.unicorn);
//=> '🦄'
console.log(String(wrapper));
//=> '/* Wrapped with wrapper() */\nfunction foo() {}'
