I just verified that Borland 5.6.4 complains of ambiguity when safe-bool and
char conversions are combined. The same is true with a void* conversion instead
of safe-bool. It works with a bool conversion instead of safe-bool, but this
makes me a bit nervous. I'll have to wait until I have a bunch of filters
implemented.
