I wonder what kinds of modern games we could make with these same ideas.

I've not used the copilot like features, but asking questions has been very useful.

    define fibfast(n)  ; Typical function notation
      if {n < 2}       ; Indentation, infix {...}
        n              ; Single expr = no new list
        fibup(n 2 1 0) ; Simple function calls

    define fibup(maxnum count n-1 n-2)
      if {maxnum = count}
        {n-1 + n-2}
        fibup maxnum {count + 1} {n-1 + n-2} n-1

    define factorial(n)
      if {n <= 1}
        1
        {n * factorial{n - 1}} ; f{...} => f({...})

  (+ 1 2 3)

Even with the exact same representation, it will speed up the no cases at the expense of slightly slowing down the yes cases (assuming that that is also what the function itself does), but since this is called on tokens with no a-priori reason to expect a match as the normal case, you’ll have more no than yes, so even if it was symmetric speed swap that'd be a win (and I think the existing way you lose more to each exception that you gain avoiding duplicating the check on matches, so it should be a bigger gain that you'd expect if it was symmetric.)

I'd love to see classic Notepad and MS Paint too.

But the most important part of notepad was the editing component, which was a standard win32 component, and wasn’t part of the leak. It’s also unlikely they’ll release it since it’s part of current windows.

You can find torrents of the source code online and dig around in it if you don't mind breaking the law (or ruining your chances of being allowed to contribute to Wine or ReactOS in the future).

Android NDK

The Android NDK is a toolset that lets you implement parts of your app in native code, using languages such as C and C++. For certain types of apps, this can help you reuse code libraries written in those languages.
