Interesting rant about Scala's issues

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.
