Todo ideas

• distinguish Val constuctors (LambdaPattern ConstansPattern SimpleValue Value)
• rename Val types to a more descriptive names; see above
• GRIN AST gen EDSL
• better name representation instead of strings
• generate unique names when branching (unique name A + branching direction = unique name B)
• efficient substitution
• type safer and easy to use AST
• add simple frontend language with grin conversion (GHC/STG -> GRIN)
• generate apply

CodeGen

• simplify/refactor LLVM codegen
• vectorisation = tagged union conversion (on branch: var-tag-node-is-tagged-union) ; better syntax for tagged union (parser + pretty printer)
• read back LLVM reduced result to Haskell data (including the heap)

GRIN framework

• scoped type environment
• scoped names ; it would make inlining easy (the idea is similar to bound)
  • HPT
  • optimisiations
  • type env

HPT

• LLVM backend for HPT IR
• inline support
• sharing analysis
