Your Help Needed
If you know Crystal, please write code for some of the tasks not implemented in Crystal.

Crystal is a programming language with the following goals:

  • Have the same syntax as Ruby, or at least as similar as possible.
  • Never have to specify the type of a variable or method argument.
  • 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.

You can ask for help on Freenode in the #crystal-lang channel.
