As I said, READ THE PIECE, forget about what you think you already know.<p>A discussion of what he actually said will be more interesting than a discussion of what you misunderstand.<p>But in response to the point you raised, the purpose of Simonyi&#x27;s system is NOT to avoid compilation errors (what you call redundant). The naming convention encapsulates precisely what programmers need to keep in their heads while they code; humans are not compilers, and the type information involved is NOT THE COMPILER OR LANGUAGE TYPE, it is the abstract (human) type.<p>It is to (1,2,3 might not be all or the only reasons) (1) speed the coding task for the human (2) speed the maintenance task for the human and (3) enhance programmer understanding of the code to eliminate errors of human logic.
