Crystal is a programming language with the following goals:

- Have a syntax similar to Ruby (but compatibility with it is not
  a goal)
- Statically type-checked but without having to specify the type
  of variables or method arguments.
- Be able to call C code by writing bindings to it in Crystal.
- Have compile-time evaluation and generation of code, to avoid
  boilerplate code.
- Compile to efficient native code.
