             Bug #: 13034
           Summary: Surprising-but-correct typo correction with
                    single-colon typo in qualified name lookup
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: All
            Status: NEW
          Keywords: quality-of-implementation
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: dgregor at apple.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified


Clang is totally correct here:

t.cpp:4:7: error: no template named 'vector'; did you mean 'std::vector'?
  std:vector<int> v;
      ^~~~~~
      std::vector
/usr/include/c++/4.2.1/bits/stl_vector.h:162:11: note: 'std::vector' declared
      here
    class vector : protected _Vector_base<_Tp, _Alloc>
          ^

and yet I am unsatisfied.

Ideally, we'd realize that this is a typo of a single colon rather than a
double colon, and not the user attempting to create a label 'std' followed by
an unqualified reference to 'vector'.
