The logic for putting ranges into the else prong is moved from AstGen to Sema. However, logic to emit multi-items the same as single-items cannot be done until TZIR supports mapping multiple items to the same block of code. This will be simple to represent when we do the upcoming TZIR memory layout changes. Not yet implemented in this commit is the validation of duplicate values. The trick is going to be emitting error messages with accurate source locations, without adding extra source nodes to the ZIR switch instruction. This will be done by computing the respective AST node based on the switch node (which we do have available), only when a compile error occurs and we need to know the source location to attach the message to.

The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better software. Even more important, however, are the end-users.
Zig is intended to be used to help end-users accomplish their goals. Zig should be used to empower end-users, never to exploit them financially, or to limit their freedom to interact with hardware or software in any way.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end-users.
This project redistributes code from other projects, some of which have other licenses besides MIT. Such licenses are generally similar to the MIT license for practical purposes. See the subdirectories and files inside lib/ for more details.
