int main(int argc, char *argv[]) {}
-----------------------------------
template_name_injection2.cpp:8:23: error: template argument for template
template parameter must be a class template or type alias template
using T = TTClass<Foo>;
-----------------------------------
clang version 4.0.1 (tags/RELEASE_401/final)
Target: x86_64-unknown-linux-gnu
-----------------------------------
Foo should resolve to a template template parameter corresponding to C++ std
14.6.1. Adding the complete namespace works as a fix (using T =
TTClass<::Foo>;)</pre>
