+// 14.8.1: In contexts where deduction is done and fails, or in contexts
+// where deduction is not done, if a template argument list is specified
+// and it, along with any default template arguments, identifies a single
+// function template specialization, then the template-id is an lvalue for
+// the function template specialization.
+
+// Here, deduction is not done to resolve fn<int> because the target type
+// is a template parameter, so we resolve to the second template, and then
+// the call to def fails because we deduce different values of Fn for the
+// two function arguments.
