Last I used it, Crystal’s compilation times are brutal. They may have fixed this (for non-production / dev iteration) with their work on an interpreter, though.

Last I used it, Crystal’s compilation times are brutal. They may have fixed this (for non-production / dev iteration) with their work on an interpreter, though. After using fast compilers, it’s really painful to go back to slow ones. That said, Crystal is a really great language, and I plan on tinkering with it again soon.
