Haskell program outputs “
As several of the comments have said, this is the Haskell RTS detecting an infinite loop at run-time. It cannot always detect such loops, but in simple cases it can.

C++ how to manage dependencies (use libraries from github for example)

How to prevent non-specialized template instantiation?
Just don’t define the class: template <typename Type> class Foo; template <> class Foo<int> { }; int main(int argc, char *argv[]) { Foo<int> f; // Fine, Foo<int> exists Foo<char> fc; // Error, incomplete type return 0; } Why does this work?
