Because it wasn't properly tested for that. Anything can have a bug in it. 
It's true that the more complicated something is, the more likely it is that 
it's going to have bugs, but the fact that something has a bug doesn't 
necessarily mean that it's overly complicated.

I admit that it surprised me how complicated std.algorithm.min is, but I don't 
think that it's all that bad. That extra complication does allow it to handle 
comparing signed and unsigned types more correctly. It's just a matter of 
fixing this one bug and adding proper tests so that it doesn't break like this 
again. And there's already a pull request to fix that (though it appears that I 
forgot to put a comment for it in the bug):
