Here’s my understanding: The older compilers don't implement as much checking at template-definition time as clang does. These older C++ compilers tended to treat templates more like macros and not do much checking on them until the template was instantiated. But the C++ standard allows (perhaps requires) additional checking at the time the template is defined.

On the other hand, I was led to believe that some folks have successfully compiled this code with at least some version of clang, so this may simply be a mistake in a certain version of clang rather than correct behavior.
