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.
See #163, #160
Toy now fits into the C spec.
Fixed#158
Addendum: MacOS test caught an error:
error: a function declaration without a prototype is deprecated in all versions of C
That took 3 attempts to fix correctly.
Addendum: 'No new line at the end of file' are you shitting me?
I had intended to solve the Advent of Code puzzles in Toy, but they
don't work without arrays. I wasn't able to enable arrays in time, so
I need to focus on doing things correctly.
The most immediate tasks are marked with 'URGENT', and a lot of tests
need writing.
I was reworking bits of the containers to address issue #131, then
realized that the table's tests depended on a specific initial size. I'm
too buggered to finish it tonight, so I'll fix it tomorrow.
