Thanks for the patch!

There's a problem though: Zig comes with some binaries (the wasm 
bootstrap), which go against of the Guix policy.
Hilton Chain and myself have take a look to this very issue, trying to 
bootstrap it properly, but its taking time.

About the tests, the zig package in nix, which is (I think) maintained 
by the zig author, uses only the behavior tests.

I did a similar package for myself in the following link, that passes 
the behavior tests:

https://git.elenq.tech/guix-packages/tree/zig.scm?id=214f27145ea93dcab99929586df3259acf77d7c9

So, yes. We are trying to add Zig. Sadly, our free-software and 
no-binaries policies don't allow us to include the package just like this.

Thanks again for your contribution.

I hope we can add a modified version of it soon to Guix.

Best,
Ekaitz
