N.B. the use of an invalid expression in a sizeof context is not valid in C++03, but the SFINAE rules were extended to cover general expressions by n2634 so I believe the code is valid in C++0x (see 14.9.2 [temp.deduct] p8 in WP n2914) and should result in a type deduction failure not a hard error. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40595
