TODO

Implement a proper type matching / checking system
- Implement subscript as an operator
  - Implement another operator
    - Figure out how to do type classes
- Implement structs again, with the .foo notation working
Implement a trace() builtin for debugging
Check if we can use DataView in the Javascript examples, e.g. with setUint32
Storing u8 in memory still claims 32 bits (since that's what you need in local variables). However, using load8_u / loadu_s we can optimize this.
Implement a FizzBuzz example
Also, check the codes for FIXME and TODO
