The point of that part of the rant is that using an integer is very not-precise, typing-wise. Having more precise typing sometimes helps.

In a little higher level language using a 3-value enum (as in Haskell, more or less) is still sufficiently efficient. And Ada language shows that often you can have both precise types (strong typing) and almost C-like efficiency.

I would agree if D actually had type-safe enums.

enum a
{
    val = 1
}
        
enum b
{
    val = 1
}

assert(a.val - b.val == 0);
