Tiny VM in OCaml - learning
(*
Some time ago I found this tutorial about writing a small VM in c.
http://blog.felixangell.com/blog/virtual-machine-in-c
Here's something similar in OCaml. Nothing super fancy and a lot of room for improvements.
But it's a start :)

Orthodox C++

Orthodox C++

What is Orthodox C++?

Orthodox C++ (sometimes referred as C+) is minimal subset of C++ that improves C, but avoids all unnecessary things from so called Modern C++. It's exactly opposite of what Modern C++ suppose to be.

Why not Modern C++?
