Summary: Prematurely diagnoses unexpanded parameter packs
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++0x
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
It looks to me that assuming resolution of core issue #778 is accepted, the
following is valid code
template<typename ...T>
struct A {
template<template<T> class ...>
struct B { };
};
template<int> struct C { };
template<long> struct D { };
int main() {
A<int, long>::B<C, D> e;
}
Clang errors out (only showing the first relevant error message):
main1.cpp:3:22: error: non-type template parameter type contains unexpanded
parameter pack 'T'
template<template<T> class ...>
