More or less the same way you do in perl5
- upgrade the sv to a dual-var type
- call the var's set_integer entry
- call the var's set_string entry
Then when you want the string form call the vars get_string
it has to check private internal flags I guess - the point is that
even in perl these weird variables are rare. We have removed flag
testing for the common cases and only have it where required.
