    33 # Features of Crystal
    34 # - Ruby-inspired syntax.
    35 # - Statically type-checked but without having to specify the type of variables or method arguments.
    36 # - Be able to call C code by writing bindings to it in Crystal.
    37 # - Have compile-time evaluation and generation of code, to avoid boilerplate code.
    38 # - Compile to efficient native code.
