@Ivan, GCC 4.7 gives:

pr16070.cc:5:20: error: no matching function for call to âBar(<unresolved
overloaded function type>)â
pr16070.cc:5:20: note: candidates are:
pr16070.cc:3:9: note: template<class T> void Bar(const T&)
pr16070.cc:3:9: note:   template argument deduction/substitution failed:
pr16070.cc:5:20: note:   couldn't deduce template parameter âTâ
pr16070.cc:4:9: note: void Bar(int)
pr16070.cc:4:9: note:   no known conversion for argument 1 from â<unresolved
overloaded function type>â to âintâ

which seems better, no?

Compare to Clang:

/tmp/webcompile/_30708_0.cc:5:15: error: no matching function for call to 'Bar'
int main() {  Bar(f); }
              ^~~
/tmp/webcompile/_30708_0.cc:4:9: note: candidate function not viable: no
overload of 'f' matching 'int' for 1st argument
void    Bar(int i) {}
        ^
/tmp/webcompile/_30708_0.cc:3:9: note: candidate template ignored: couldn't
infer template argument 'T'
void    Bar(const T& t) {}
        ^

so g++ is not as good as clang, but it got closer at GCC 4.7. Perhaps g++ could
handle better the "unresolved overloaded function type"?

(Gosh! how can clang be that good at this?)
