At some point it makes more sense to switch to Crystal.

Crystal is a non-starter for me since the entire appeal of Ruby is the runtime metaprogramming.

Crystal has a nice AST based Macro system. IMHO it makes up for it. The problem with Crystal is no direct support for Windows OS compilation which is a non starter for many developers.

The Crystal macro system is pretty advanced though, I think it works very well to replace metaprogramming.
