 - 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?
+  - Clean up Subscript implementation - it's half implemented in the compiler. Makes more sense to move more parts to stdlib_types.
 - 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
+- Parser is putting stuff in ModuleDataBlock
+  - Surely the compiler should build data blocks
 - Make prelude more an actual thing
-  - Merge in type3types.LOOKUP_TABLE
+  - Merge in compiler.INSTANCES
+  - Make it less build in - have a environment class of some kind
 - 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 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?
+  - Functions don't seem to be a thing on typing level yet?
