born-and-raised

Crystal is a programming language with the following goals:

Why?

We love Ruby's efficiency for writing code.

We love C's efficiency for running code.

We want the best of both worlds.

We want the compiler to understand what we mean without having to specify types everywhere.

We want full OOP.

Oh, and we don't want to write C code to make the code run faster.
