Boost C++ Libraries: Ticket #5666: is_class documented as yielding "true" for unions, but documentation contradicts that

Thomas Heller — Thu, 30 Jun 2011 21:21:33 GMT

Even the cited standard paragraph states this:

3.9.2: "unions, which are classes capable of containing objects of different types at different times, 9.5;"

schaub.johannes@… — Thu, 30 Jun 2011 21:24:53 GMT

Also at 9p4: "A union is a class defined with the class-key union; its members are public by default and it holds only one data member at a time (9.5)." and the remaining text of the spec.

C++0x FDIS explicitly excludes a union type for is_class. I attached a patch to sync with this.
