I really enjoy thinking about such issues. I actually spend a lot of time considering whether to use type prefixes or suffixes, [] or <>, and ultimately settled on “<>”.

In my opinion, the change from `<>` to `[]` is a minor adjustment. `<>` is already widely adopted, and I don't want to break with convention for such a small benefit.

The position of the type is similarly considered. Postfixing the type has some advantages over prefixing it, but those advantages aren't sufficient for me to break with convention.
