I originally introduced
Optionalwith that name because I thought that it wouldn't be possible for users to passOption<T>to Roto. The nameOptionalwould then make it easier to distinguish Rust'sOption<T>from Roto'sOptional<T>. However, with thetransformsystem in theReflecttrait, it is now just possible to pass aOption<T>to Roto and the transformation to the proper Roto type will happen automatically. Therefore, I don't want to bother users with the distinction anymore.
