The latter results in undefined behavior if p is null, so if get() has got
your goat, your stuck with
BOOST_SMART_PTR_CONVERSION and "if (!p)".
Here's a safe option to avoid having to choose between using the implicit
pointer conversion and get(): define operator! and use "if (!p)" to test for
null and "if (!!p)" to test for non-null. I don't like the looks of it,
either, but that would change over time, and even better, I'd love to see how
long before people start referring to the "test for non-null operator". :-)
