Absolutely, it's a cool little bit of code that does a single job well.

Some suggestions to whoever wishes to run further with this ball;  I missed a method/function for converting an int64 into hex, that would be very easy to add and not possible any other way.  Also a potentially lossy conversion to double (full marks if it can return an extra value indicating if truncation took place).  tonumber(tostring) is clumsy and rather slow.

I think __pow should be overloaded with second integer argument for fast calculations of powers-of-two.

(And it would be cool if i64[1] would return the least significant byte, etc, with #i64 always being 8.  __call can be used for a bit slice operator)
