> Rust has a very powerful type system, and combining that with lifetimes
If you don't count lifetimes, Rust's type system isn't really more powerful or complex than, say, that of Swift. There are no dependent types here. There are no type families. There aren't even higher-kinded type parameters.

The type system grows more powerful (and more complex) every time I revisit Rust, it seems.
I'm glad, as an increasingly powerful type system facilitates abstractions that were once painful, slow, unsafe, or impossible, but it is complex.
