This makes sense. I was hesitant to "just str()" it because the whole
point of format() (or, at least, the biggest point) is that it makes
things safely escaped for insertion into a SQL statement--no malicious
If I did it the way you suggest, however, and do something like
STRING(str(unknown_thing)) so that it was sure to be escaped properly,
that seems like it would be a useful thing.
