Thanks for doing this!

Oops, just noticed this is a draft. Apologies for the premature review.

[andrewrk]

yeah!!

What's the recommended way of updating existing code for this? I have so many tests... D=

Basically just doing what I did in this pr, slap a bunch of trys in front of calls to std.testing.expect* and everything should just work.

Yeah kind of... definitely not that easy if you wrote any kind of expectEqual functions yourself. Especially not when they're recursive (like with a tree).
I'll have to update this for some other time.

find -name "*.zig" -exec sed -i 's/std.testing.expect/try std.testing.expect/g' '{}'

Should update most things correctly 😁
Self-made recursive test functions shouldn't be a problem either, you just have to slap the explicit error set (which is well-known) onto you functions instead of inferring the error set
