Crystal Programming Language

See the description above. Crystal is a high-level general-purpose, object-oriented programming language, designed and developed by Ary Borenszweig, Juan Wajnerman, Brian Cardiff and more than 530 contributors.[5] With syntax inspired by the language Ruby,[6] it is a compiled language with static type-checking, but specifying the types of variables or method arguments is generally unneeded. Types are resolved by an advanced global type inference algorithm.[7][8] Crystal is currently in active development. It is released as free and open-source software under the Apache License version 2.0.
