c) Don't use settype(). Settype is bad. You never ever should forcefully
convert objects between types. That's one of the most horrible features of
C++. As applied to this situation - forbid settype() on or to any
non-basic (i.e., not string/number) type. You really don't want it if you
go for clean OO design.
