Johan B.W. de Vries 6a1f4fc010 Replaces type3 with type5
type5 is much more first principles based, so we get a lot
of weird quirks removed:

- FromLiteral no longer needs to understand AST
- Type unifications works more like Haskell
- Function types are just ordinary types, saving a lot of
  manual busywork

and more.

TODO

  • Decide between lineair types / uniqueness vs garbage collector

  • Rename constant to literal

  • Implement a trace() builtin for debugging

  • Check if we can use DataView in the Javascript examples, e.g. with setUint32

  • Implement a FizzBuzz example

  • Also, check the codes for FIXME and TODO

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

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

    • Implement q32? q64? Two i32/i64 divided?
  • Have a set of rules or guidelines for the constraint comments, they're messy.

  • calculate_alloc_size can be reworked; is_member isn't useful with TYPE_INFO_MAP

  • Parser is putting stuff in ModuleDataBlock

    • Surely the compiler should build data blocks
    • Also put the struct.pack constants in TYPE_INFO_MAP
  • 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

  • Read https://bytecodealliance.org/articles/multi-value-all-the-wasm

  • Implement type class 'inheritance'

  • Remove FunctionInstance, replace with a substitutions dict

    • See phft2 in fromast.py:expression_function_call
  • Move unify into the typeconstraints (or other way around) - it's done on two levels now (partly in solver)

  • Rework type classes - already started on a separate dir for those, but quite a few things are still in other places.
