Are there any other examples? I'm especially interested in cases where
the non-utf8 string gets upgraded but actually doesn't change.
Although I strongly recommend against fussing over the internal
encoding except for performance reasons, encoding::warnings, available
from CPAN is a valueble module in finding these cases.
Don't forget to remove it before releasing something for production.
Automatic scalar upgrading is a very important feature, and not at all
scary.
(It happens with numbers too: the integer 1 is automatically upgraded
internally to a float, whenever that is needed.)
