Arrays would be a reference type with runtime sizing.

  • Parse array expressions
  • Extend the type system with array types
  • Compile array expressions
  • Allocate/deallocate memory for arrays (special methods emitted into each compilation)
  • Negative sizes cause termination
  • Reference semantics in parameter passing
  • Range checking
  • Negative size in new causes termination
  • Consider: compile-time constant arrays?
  • Update the language specification
  • Ability to get a raw pointer for interop (to skip reference count updating) - maybe with Length property on arrays #70?

Probably can leave multidimensional arrays out for now.
