Crystal is directly inspired by Ruby, so I don't think is too far of a bridge! I programmed Ruby for years before learning Rust, and aspects of Rust's library and language inspiration from Ruby are obvious to me: the closure syntax closely resembles Ruby's blocks, for example, and much of the core iterator APIs match their Ruby counterparts. It's a very different language overall, of course! (Then of course there's the part where many early Rust contributors came from the Ruby community.)
