When Sema sees a store_node instruction, it now checks for the possibility of this pattern: %a = ret_ptr %b = store(%a, %c) Where %c is an error union. In such case we need to add to the current function's inferred error set, if any. Coercion from error union to error union will be handled ideally if the operand is comptime known. In such case it does the appropriate unwrapping, then wraps again. In the future, coercion from error union to error union should do the same thing for a runtime value; emitting a runtime branch to check if the value is an error or not. `Value.arrayLen` for structs returns the number of fields. This is so that Liveness can use it for the `vector_init` instruction (soon to be renamed to `aggregate_init`).
A general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

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.
