-**Consistent context-free syntax.** Cpp2 is designed so that there is one general way to spell a given thing, that works consistently everywhere. All Cpp2 type/function/object/namespace/module/etc. declarations use the unambiguous and context-free syntax **"_name_ `:` _kind_ `=` _statement_"**. The `:` is pronounced **"is a,"** and the `=` is pronounced is pronounced **"defined as."**
