// Default versions of mixed arithmetic, these just construct a temporary
// from the arithmetic value and then do the arithmetic on that, two versions
// of each depending on whether the backend can be directly constructed from type V.
//
// Note that we have to provide *all* the template parameters to class number when used in
// enable_if as MSVC-10 won't compile the code if we rely on a computed-default parameter.
// Since the result of the test doesn't depend on whether expression templates are on or off
// we just use et_on everywhere.  We could use a BOOST_WORKAROUND but that just obfuscates the
// code even more....
