$PRGNAM: $PRGNAM (The Crystal Programming Language)
$PRGNAM:
$PRGNAM: Crystal is a programming language with the following goals:
$PRGNAM: .Have the same syntax as Ruby, or at least as similar as possible.
$PRGNAM: .Statically type-checked but without having to specify the type of variables or
$PRGNAM:    method arguments.
$PRGNAM: .Be able to call C code by writing bindings to it in Crystal.
$PRGNAM: .Have compile-time evaluation and generation of code, to avoid boilerplate code.
$PRGNAM: .Compile to efficient native code.
