Yes, C++11 has relaxed the constraints and supports variables of internal
linkage as well. E.g. a variable declared with the static keyword in namespace
scope is feasible now. But your example does not provide a variable of either
internal or external linkage: Variable pi is an automatic variable and thus has
*no* linkage at all. Those are no valid template arguments in C++11 either.
Without any form of linkage, a compiler cannot associate an address constant or
reference constant with the variable.
