TODO

• Decide between lineair types / uniqueness vs garbage collector

  • https://borretti.me/article/how-australs-linear-type-checker-works

• Rename constant to literal

• 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

• Allocation is done using pointers for members, is this desired?

• Functions don't seem to be a thing on typing level yet?

• static_array and tuple should probably not be PrimitiveType3, but instead subclass AppliedType3?

• See if we want to replace Fractional with Real, and add Rational, Irrationl, Algebraic, Transendental

• Does Subscript do what we want? It's a language feature rather a normal typed thing. How would you implement your own Subscript-able type?

• Have a set of rules or guidelines for the constraint comments, they're messy.

• Find pytest.mark.skip

• There's a weird resolve_as reference in calculate_alloc_size

  • Either there should be more of them or less
  • At first glance, looks like failure in the typing system
  • Related to the FIXME in phasm_type3?
  • Related: Parser is putting stuff in ModuleDataBlock

• Casting is not implemented except u32 which is special cased

• Make prelude more an actual thing

  • Merge in type3types.LOOKUP_TABLE

• Implemented Bounded: https://hackage.haskell.org/package/base-4.21.0.0/docs/Prelude.html#t:Bounded

• Try to implement the min and max functions using select

• Filter out methods that aren't used; other the other way around (easier?) only add __ methods when needed

• Move UnaryOp.operator into type class methods

• Move foldr into type class methods

• PrimitiveType is just the type, nothing primitive about it (change the name). u32 are still basic types or something.

• Clean up Subscript implementation - it's half implemented in the compiler. Makes more sense to move more parts to stdlib_types.

• Type constuctor should also be able to constuct placeholders - somehow.

• Make struct a type constructor?

• Add InternalPassAsPointer to Struct?
