fizzbuzz's Issues

Re-organise the source.

It was done in a rush and is a bit dis-organised. The compiler should probably go in its own module.

Strings aren't really implemented.

At the moment, FizzBuzz just needs strings as an arg for print, but the compiler still has them as a 1st class type next to number.

So anything we can do with numbers (the binary ops) we should either support for strings, or barf with a type error.

Add proper tests.

Use cargo test to run and validate the tests properly.

Add `elif`.

if (a) {
  ...
} elif (b) {
  ...
} else {
  ...
}

Print more integers properly.

Right now we can only print numbers between 0 and 999 correctly, and even then it's with leading spaces.

Ideally we could do negatives and more digits, without the leading spaces. Ideally we'd just call printf but Cranelift doesn't support varargs yet. So a bespoke version is going to need to reserve storage to store digits, LSB to MSB. It'll need to either reverse the bytes in storage and then call puts or it could putchar the digits in the right order.
