             Bug #: 11306
           Summary: Variadic template fix-it suggestion
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++0x
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: chris at bubblescope.net

A few times I have written (note the ... in the wrong place on the template)

template<typename Args...>
int f(Args...)
{ }

The current error is the not very helpful:

t.cc:1:23: error: expected ',' or '>' in template-parameter-list
template<typename Args...>
                      ^
t.cc:1:26: error: expected unqualified-id
template<typename Args...>
                         ^
Something nicer, with a fix-it, would be nice.

The similar:

template<typename... Args>
int f(Args args...)
{ }

Produces the nicer (but still no fixit)


t.cc:2:5: error: declaration type contains unexpanded parameter pack 'Args'
int f(Args args...)
    ^ ~~~~
