Crystal's syntax is somewhat similar to Ruby's, but its actual semantics (and type system) are fundamentally different. In particular, `method_missing` and other fundamentally dynamic things that make Ruby feel like Ruby can't be done in Crystal, at least not without extensive runtime support. (I haven't looked at this implementation, but I suspect that they end up doing similar things in C++ for the same reason.) |
