- Small (same scale as C) and basically C like
- Match actual machine model, better (more modern) than C
- "Higher level" features such as inheritance and RTTI come from libraries. As with C++ you shouldn't pay for what you don't use but we should do better than C++.
- Exceptions may be the exception to the above rule.
- Memory model which supports threading and thread primitives.
- Thread primitives support the following models:
- Pipes (thread safe Queue messaging system)
- parallel algorithms (parallel reduce, for_each, etc. - see Intel Thread Building Blocks)
- simple atomic increment/decrement for shared structures (ref counting for immutable objects and copy-on-write)
- Full compile time introspection (runtime introspection as a library).
- Support the C linkage model
- "Semantic Spaces"
- Library versioning (part of semantic spaces?)
- Value semantics
- Some level of concept support
- Indexed types (Not quite sure how to build this)
- Functions (with state) are first class
