WIP functions working, untested, memory issues, read more

I've ripped out the deep copying, and flattened the bucket usage, but
this results in no memory being freed or reused for the lifetime of the
program.

This is shown most clearly with this script:

```toy
fn makeCounter() {
	var counter: int = 0;

	fn increment() {
		return ++counter;
	}

	return increment;
}

var tally = makeCounter();

while (true) {
	var result = tally();

	if (result >= 10_000_000) {
		break;
	}
}
```

The number of calls vs amount of memory consumed is:

```
function calls -> memory used in megabytes
1_000 -> 0.138128
10_000 -> 2.235536
100_000 -> 21.7021
1_000_000 -> 216.1712
10_000_000 -> 1520.823
```

Obviously this needs to be fixed, as ballooning to gigabytes of memory
in only a moment isn't practical. That will be the next task - to find
some way to free memory that isn't needed anymore.
