Clang does only marginally better because of its selective typedef unwrapping
and avoiding printing back expressions, but then it goes and prints all
candidates:
/tmp/webcompile/_7569_0.cc:10:13: error: invalid operands to binary expression
('ostream' (aka 'basic_ostream<char>') and '<overloaded function type>')
{ std::cout << v.size; }
