+ * ll_template_cast<T>(some_value) is for use in a template function when
+ * some_value might be of arbitrary type, but you want to recognize type T

+ *
+ * It's designed for use with pointer types. Example:
+ * @code

+ * };
+ *
+ * template <class REALCLASS>

+ *
+ * Why is this better than dynamic_cast<>? Because unless OtherClass is

+ * @code
+ * OtherClass other;
+ * SpecialClass* ptr = dynamic_cast<SpecialClass*>(&other);
+ * @endcode
+ * to say nothing of this:
+ * @code

+ * LL_TEMPLATE_CONVERTIBLE(dest, source) asserts that, for a value @c s of
+ * type @c source, <tt>ll_template_cast<dest>(s)</tt> will return @c s --
+ * presuming that @c source can be converted to @c dest by the normal rules of
+ * C++.
+ *
+ * By default, <tt>ll_template_cast<dest>(s)</tt> will return 0 unless @c s's
+ * type is literally identical to @c dest. (This is because of the
+ * straightforward application of template specialization rules.) That can
+ * lead to surprising results, e.g.:
+ *
+ * @code
+ * Foo myFoo;
+ * const Foo* fooptr = ll_template_cast<const Foo*>(&myFoo);
+ * @endcode
+ *
+ * Here @c fooptr will be 0 because <tt>&myFoo</tt> is of type <tt>Foo*</tt>
+ * -- @em not <tt>const Foo*</tt>. (Declaring <tt>const Foo myFoo;</tt> would
+ * force the compiler to do the right thing.)
+ *
+ * More disappointingly:
+ * @code
+ * struct Base {};
+ * struct Subclass: public Base {};
+ * Subclass object;
+ * Base* ptr = ll_template_cast<Base*>(&object);
+ * @endcode
+ *
+ * Here @c ptr will be 0 because <tt>&object</tt> is of type
+ * <tt>Subclass*</tt> rather than <tt>Base*</tt>. We @em want this cast to
+ * succeed, but without our help ll_template_cast can't recognize it.
+ *
+ * The following would suffice:
+ * @code
+ * LL_TEMPLATE_CONVERTIBLE(Base*, Subclass*);
+ * ...
+ * Base* ptr = ll_template_cast<Base*>(&object);
+ * @endcode
+ *
+ * However, as noted earlier, this is easily fooled:
+ * @code
+ * const Base* ptr = ll_template_cast<const Base*>(&object);
+ * @endcode
+ * would still produce 0 because we haven't yet seen:
+ * @code
+ * LL_TEMPLATE_CONVERTIBLE(const Base*, Subclass*);
+ * @endcode
+ *
+ * @TODO
+ * This macro should use Boost type_traits facilities for stripping and
+ * re-adding @c const and @c volatile qualifiers so that invoking
+ * LL_TEMPLATE_CONVERTIBLE(dest, source) will automatically generate all
+ * permitted permutations. It's really not fair to the coder to require
+ * separate:
+ * @code
+ * LL_TEMPLATE_CONVERTIBLE(Base*, Subclass*);
+ * LL_TEMPLATE_CONVERTIBLE(const Base*, Subclass*);
+ * LL_TEMPLATE_CONVERTIBLE(const Base*, const Subclass*);
+ * @endcode
+ *
+ * (Naturally we omit <tt>LL_TEMPLATE_CONVERTIBLE(Base*, const Subclass*)</tt>
+ * because that's not permitted by normal C++ assignment anyway.)
