Well, they could do what they did with map iteration: make it happen arbitrarily different each program execution.

Breaking it randomly and requiring debugging is not the same as telling you you're doing something wrong and where.

Worked for maps :)

The same exact argument applies. The code was broken to begin with, the implementation behavior did not break anything.

And, just like with map iteration ordering, it's very difficult/impossible for the compiler to say "hey don't depend on this!".

The only way that I can think of to get this concept (that import order in code and init() order in runtime are unrelated) is to have things break.

I guess I've personally never seen the value of static initializers (in other languages at least), they always seem like the source of hard-to-find bugs. So perhaps that's really where my complaint is. Is there a compelling use for them in Go over explicit initialization?

I suppose if the runtime randomizes things, at least you would never experience it consistently working in the first place, so maybe the issue wouldn't ever come up.

Right, that's the idea.

Regarding static initializers, I use them for precompiling regexps and templates, but not much more than that.
