Rvalue references to functions are allowed, but expressions of function type
are always lvalues. See, for instance:

[expr.call]p10: A function call is an lvalue if the result type is an lvalue
reference type or an rvalue reference to function type.

[expr.static.cast]p1: The result of the expression static_cast<T>(v) is the
result of converting the expression v to type T. If T is an lvalue reference
type or an rvalue reference to function type, the result is an lvalue.
