The current working draft has a type-trait decay in 184.108.40.206 [meta.trans.other].
Its use is to turn C++03 pass-by-value parameters into efficient C++0x pass-by-rvalue-reference parameters. However, the current definition introduces an incompatible change where the cv-qualification of the parameter type is retained. The deduced type should loose such cv-qualification, as pass-by-value does.
In 220.127.116.11 [meta.trans.other] change the last sentence:
Otherwise the member typedef type equals U.
In 22.4.4 [tuple.creation]/1 change:
where each Vi in VTypes is X& if, for the corresponding type Ti in Types, remove_cv<remove_reference<Ti>::type>::type equals reference_wrapper<X>, otherwise Vi is decay<Ti>::type.
