@catmando not sure if you saw this discussion previously in Gitter, but I have been thinking that a portable Hyperloop that can run atop Amber or even Lucky frameworks for Crystal might be very attractive for the communities. It could be argued that having Hyperloop / Opal on these provides a more isomorphic platform even though it's not one-to-one per se. Nonetheless, it would very much expand desirability for those hunting speed while keeping a primarily Ruby environment.
