Re: member templated definitions out of class scope

With gcc (3 or 4) the member template definition out of class scope
below compiles fine. But with Sun's CC 5.9, it fails with:

"main.cpp", line 7: Error: Could not find a match for Foo<T,
Policy<struct>>::bar<Foo<T, Policy<struct>>::U>(U).

This seems like a bug to me, has anyone else encountered this? Is
there any workaround beside putting the definition inside the class
decl?

Thanks much.
