Re: [boost] review request: addition to type_traits library of is_less_comparable<T, U> and others

Since is_convertible_to is always implied, and any type can be converted -- using the term loosely -- to no type, "void" might not be confusing.  The name used in this context could be left to reviewers to choose.

how does is_convertible_to<> handle void? ie are all types considered convertible to void? Tony
