Ruby works, they either need to restrict the language, include

a call to
a helper function like `send(_var_a, SYMBOL(":+"), _var_b);`,

that the compiler backend can eliminate this in some cases.
It's implemented on top of Objective-C.
This makes sense, Objective-C can cope with classes that change
at runtime. Singleton methods are probably more challenging,
though...
