Even though I now implemented VarOr, I guess you might want to be careful
about that and use a native oleaut32 instead, since oleaut32 contains
tons of variant calculation functions (mul, add, and, xor, various
conversions, div, round), so if there's *any* bug in there affecting
some function your program uses, boom goes your data eventually.
That's why I'd use native oleaut32 for production use.
OTOH I'm still waiting for some builtin oleaut32 test reports ;)
