I disagree but perhaps it's on semantics... A better statement would be: If the boxing/unboxing matters, don't use a language with objects. Use one that gives you value types to manipulate and serialize into. For some things, like Regexp, the language has almost zero overhead-- because it's done in C/bare metal. Additionally you could provide which languages/runtimes one should use.
