I had vague plans to bug Graham (yay, spelling!) about proposing wrapt for inclusion in 3.5 (possibly split between functools and types rather than as a completely new module, though).

functools.wraps was always intended as a near term workaround that, like most sufficiently effective workarounds, ended lasting years before its limitations irritated anyone enough for them to go back and do it right :)

Nick.
