Repr

• without a value repr for BOZs, we're forced to delay evaluating function & operation arguments until we know the function. since we need to implement the special BOZ case

Small refactorings

• Many AST nodes could be upgraded to use NonEmpty - some appear to be nonsensical for the empty list case (e.g. Declarator with ArrayDecl)
  • May need another newtype to work with AList
• How to handle empty ALists
  • Empty ALists are hard to give SrcSpans to (but probably OK to do so)
  • Some syntax allows omitting brackets for empty lists
  • Maybe AList fixes the problem, but now we have Just [] and Nothing
  • Ideal solution is probably more AList-likes that encode some extra syntactic info while storing a regular list. Large scale change
  • For now, moved ExpFunctionCall and StCall from Maybe AList to AList, with notes on problematic spans
