If the problem is stated as you want a dynamic class to create instances where you call dynamic methods, then yes you need Ruby.

However, that is basically a lookup table using string based dispatch to decide what to execute, and such a lookup table can be done in anything.

Crystal "does" have dynamic methods if you are willing to override method_missing.

No, the dispatch is still decided during compilation.
