New Features

• package system
• Improved PDB support with code inspection
• typeid type (also a keyword)

• Parameteric polymorphic union type:
  • union(T: typeid, N: int) {int, T, [N]T}
• bit_set type:
  • bit_set[Some_Enum];
  • bit_set['A' .. 'Z'];
  • bit_set[0..8; u16];
• cstring type (useful for interfacing with C libraries)
• in binary operator for map and bit_set types:
  • x in y
• Parametric polymorphic signature changes with polymorphic names:
  • new :: proc($T: typeid) -> ^T {}
  • make_int_array :: proc($N: int) -> [N]int {}
  • foo :: proc($N: $I, $T: typeid) {}
• auto_cast unary operator
• Explicit inline and no_inline on procedure calls

  • #assert compile time assert
  • expand_to_tuple for (fixed length) arrays
  • typeid_of

• Diverging procedures proc() -> ! (no return)
• using Foo :: enum {A, B, C}; f := A;
• Foo :: enum {A, B, C}; len(Foo)
• New context features:
  • temp_allocator
  • logger (Still in development)
  • Assigning directly to context parameters creates a new context
  • (context is scope based)
• New compiler flags:
  • -lld (use LLD as the linker on Windows)
