Why are delegates (as in `val a: Int by lazy { 5 }` not an interface? Instead they are weird classes that have to have certain methods without specifying an interface...

I would like to write a `and` infix function that creates a delegate that combines two others, but I'm afraid that won't be possible because of this

All operators are implemented without interfaces, too. It’s just the convention. But there are `ReadWriteProperty` and `ReadOnlyProperty` to aid with this, which implements the necessary functions for `var` and `val` delegates, respectively
