 - `@kindof(<ty>)`: gives an u8 integer describing the kind of type as an index to array `[Builtin, Struct, Enum, Union, Ptr, Slice, Opt, Func, Template, Global, Const, Module]`
 - `@Any()`: generic parameter based on inference, TBD: this will ake arguments in the future that restrict what is accepted
 - `@error(...<expr>)`: emit compiler error, if reachable, and use arguments to construct a message, can display strings and types
+- `@ChildOf(<ty>)`: returns the child type of the `<ty>`, works for pointers and optionals (`@ChildOf(?u8) == u8`)
