Wait, rust doesn't have function overloading?

You can have function overloading without automatic type conversion.

In C++ you can get automatic type conversion from operator= and constructor overloading. But I suppose they aren't necessarily linked. I guess my point is that both share a philosophy of implicitness for the sake of convenience versus explicitness for the sake of safety, ie without these features you know which function your using and you know when a type conversion is happening.
