The problem was that types of non-anytype parameters were being included as part of the check to see if generic function instantiations were equal. Now, Module.Fn additionally stores the information for whether each parameter is anytype or not. `generic_poison` cannot be used to signal this because the type is still needed for comptime arguments; in such case the type will not be present in the newly generated function prototype. This presented one additional challenge: we need to compare equality of two values where one of them is post-coercion and the other is not. So we make some minor adjustments to `Type.eql` to support this. I think this small complexity tradeoff is worth it because it means the compiler does much less work on the hot path that a generic function is called and there is already an existing matching instantiation. closes #11146

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.
