Announcing Rust 1.19
One thing that recently surprised me is that Rust lacks default values and named arguments for functions.<p>Some consider it a counterpattern or bad memory to be able to not fill out all parameters or reference them by name. However some interfaces easily require like 50 different function parameters that cannot be removed in a simple way and they all make sense in different configurations. Without default values and named parameters you're lost there. I don't get this design decision on Rust side at all.
