* Add reference handling to tuples Signed-off-by: Evelyn LePain <ava.lepain@gmail.com> * Remove template template type because pair isn't working Signed-off-by: Evelyn LePain <ava.lepain@gmail.com> * amalgamate std::tie changes Signed-off-by: Evelyn LePain <ava.lepain@gmail.com> * allow the elation of a move by removing the ref requirement Signed-off-by: Evelyn LePain <ava.lepain@gmail.com> * force all number_xxx_t to be interchangeable Signed-off-by: Evelyn LePain <ava.lepain@gmail.com> * Finally got amalgamate to work correctly Signed-off-by: Evelyn LePain <ava.lepain@gmail.com> * remove const version, add a test case for scrambled number representations. Signed-off-by: Evelyn LePain <ava.lepain@gmail.com> * Use the logical set of requirements instead of decltype because VS 2015 doesn't like it Signed-off-by: Evelyn LePain <ava.lepain@gmail.com> --------- Signed-off-by: Evelyn LePain <ava.lepain@gmail.com>
