Proposed resolution (October, 2010):

If T is an lvalue reference to object type[Drafting note: with this change to the wording, an attempt to cast a function lvalue to either an lvalue or rvalue reference will be ill-formed because the function-to-pointer conversion will be applied to the operand and the resulting operand base type will be incompatible with the target base type.]or an rvalue reference to function type, the result is an lvalue; if T is an rvalue reference to object type, the result is an xvalue; otherwise, the result is a prvalue and the lvalue-to-rvalue (7.3.2 [conv.lval]), array-to-pointer (7.3.3 [conv.array]), and function-to-pointer (7.3.4 [conv.func]) standard conversions are performed on the expression v...
