For some operations it's actually easy to optimize for simple types, because `if std::mem::needs_drop::<T>()` is a valid conditional: https://doc.rust-lang.org/

For some operations it's actually easy to optimize for simple types, because `if std::mem::needs_drop::<T>()` is a valid conditional: https://doc.rust-lang.org/nightly/std/mem/fn.needs_drop.html https://doc.rust-lang.org/nightly/std/mem/fn.needs_drop.html But not everything can be fit into that. But there's a lot that can be done. And a lot of generic code can be omitted when instantiated for simpler types, etc.
