Also, I think "hard to write" is meant as "require that critical or dangerous details are written explicitly; if a feature adds convenience for writing at the expense of reading, it should be avoided". (Type inference, overloads and reflection come to mind)

I think (hope) that no one is advocating making a language verbose or complex for it's own sake.

Like Rust? Rust does most of those things wrt explicit dangerous behaviour.

Exactly.

Thanks, I edited my comment to be more readable.
