Having written a lot of C++, constructors are a bad idea. Two main reasons:

1. Error handling is difficult - they don't return anything, so you are forced to use exceptions, and throwing exceptions in constructors is awkward. Go doesn't even have exceptions so it can't do that.

2. They don't have names. Often this is fine - you only have one way to construct an object. But if you have more than one, then you have two unnamed functions that do different things. And if they have the same parameters you end up with crazy workarounds like adding dummy parameters.

The way Rust does it is far superior. Basically you have a static function that creates the object. It's a normal function, so it can return errors (or the object), and you can name it, so you can have `Circle::new_with_radius(float r)` and `Circle::new_with_diameter(float d)` with no confusion.

Much better.
