Future plans:
* Split compiler into IR generation, IR optimization, and target-specific bytecode emitter
* Globals (requires a separate mmaped segment in JIT compiler)
* Pointers: pointer types, address-of operator (&), dereferencing, scope-based lifetime tracking in interpreter
* Function overloading: separate functions from values (again) in interpreter, allow casting to specific function type to take function value
* Const propagation: annotate expression AST nodes that are computable in compile-time
* Generic parameters: can be either values or `t : type`, but always compile-time

Interpreter backlog:
* Fix identifier resolution for functions & variables
* Replace tree-walking interpreter with IR-based interpreter (invalidates the previous item)
* C FFI (foreign functions)
Aarch64 compiler backlog:
* Rewrite using IR (compiler_v2.cpp first, then swap with the old one)
* Struct fields in structs (initialization & field access)
* Struct function arguments & return values
* Arrays
Aarch64 compiler backlog: (empty!)
IR backlog:
* Structs & arrays: structs indexed by field index, make sure the representation allows for SROA
Optimizer plans:
* Inlining: track function IR size (number of nodes will do), substitute its code instead of calling if it is small enough (pay attention to recursion)
* Constant folding & propagation: if all node arguments are `const` nodes, replace the current node with the computed value
* Arithmetic simplification: replace a+0 with a, etc
* Arithmetic simplification: replace a+0 with a, etc (maybe also replace `var+const+const` with `var+const` for array/struct access)
* Branch removal: `if` nodes with condition nodes being `const` are replaced with unconditional jumps
* Jump removal: `jump` that jumps to the immediate successor node is removed
* Dead code elimination: DFS from function `return` nodes & impure function calls, remove all nodes not visited (make sure to not remove function arguments)
