Hi,

Here's a simple program:

#include <algorithm>
#include <vector>

int main()
{
   std::vector<int>  vec;
   count(vec.begin(), vec.end(), 0);   // shouldn't this be std::count ?
}

The above compiles successfully, but I think it shouldn't. I expect a
message like "error: `count` not declared in scope" because I meant to
say std::count. Isn't this a bug, or am I missing something?
