呃，估计没有，可否做个 crystal 的简介？以及它为什么特别？

• Ruby-inspired syntax.
• 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.

看这介绍我觉得 Matz 应该把作者拉进 Ruby 核心团队。
