These aliases make pointers and references look more like real types. See https://simonwo.net/code/clearer-cpp-types for more.
View cleartypes.h
#pragma once
/* These type alias templates (introduced in C++11) allow
* us to template typedefs (via a different syntax).
*
* Here we are templating generic pointer and reference types
* so we could write ptr<T> instead of T*.
