We have classes and structs:
Classes:
- Default Storage: GC Heap
- Indirection Overhead: Yes
- Semantics: Reference
- Passed By: Copying the Data's Address
Structs:
- Default Storage: Stack
- Indirection Overhead: No
- Semantics: Value
- Passed By: Copying the Data (except where the compiler can determine
it can safely and more efficiently pass by reference...at least, IIUC)
Signatures:
- Default Storage: Heap (with help of scope so won't be GC'd)
- Indirection Overhead: Yes, one layer, no other way to do it if the
backend can't optimize it out
- Semantics: Reference
- Passed By: Copying a pointer static array around (ref+scope can make
this near free)
- Implementation support: Classes and structs
