Inducing failure but not getting OutOfMemory back is not as much of a problem as never inducing failure when it was expected to be induced, so treating them differently and allowing them to be handled differently by the caller is useful. For example, the current implementation of `std.HashMapUnmanaged.getOrPutContextAdapted` always tries to grow and then recovers from OutOfMemory by attempting a lookup of an existing key. If this function is used (i.e. from `std.BufMap.putMove`) with `checkAllAllocationFailures`, then we'd have previously triggered `error.NondeterministicMemoryUsage`, but the real cause is that `OutOfMemory` is being recovered from and so the error is being swallowed. The new error allows us to both understand what's happening easier and to catch it and ignore it if we're okay with the code we're testing handling `error.OutOfMemory` without always bubbling it up.

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.
