Yes, I also tried other compilers, and all of them fail. But in [temp.local] it
is explicitly stated that "the name of a member of the class template hides the
name of a template-parameter of any enclosing class templates (BUT NOT A
TEMPLATE-PARAMETER OF THE MEMBER IF THE MEMBER IS A CLASS OR FUNCTION
TEMPLATE)". (Bold by me, that's the case of this bug.)
