Can it work with functions as arguments?

[bugeats]

Neat project. It doesn't seem to cache if a named function is used as a argument to the memoized function. Is this possible with WeakMap/Map?

It should work for named functions.

function caller( fn ) {
  return fn();
}

function rand() {
  return Math.random();
}

const mem = memoize( caller );

mem( rand ) === mem( rand ); // true

Can you post an example of what you're trying that doesn't seem to work?
