Subject: Re: Ruby tainting on primitives

We would preserve all the semantics. Let me explain.

For example, when the user tries to taint a Fixnum, instead of throwing 
a freeze error, we would upgrade the Fixnum into a Bignum.
In other words, we can box primitives when the user tries to taint.
Tainted numbers would obviously have a performance hit due to the 
unboxing, but I don't expect performance regressions for code that does 
not taint Fixnums.
