I do agree that blindly using unboxed types (like Perl 6's int) is a Bad Idea. Actually, all uses of unboxed types, except in very tightly contained and verified places, are potential disasters waiting to happen.

I'd much rather the Perl 6 compiler being able to infer when it is safe to use unboxed types, and only apply unboxing optimisations when it is sound to do so. At least, that is my goal in my work on Perl 6 to Parrot codegen as part of Pugs.
