--- Comment #4 from Joseph Rushton Wakeling <[email protected]> --- One thing I don't understand here: why is the missing symbol not detected _anyway_ regardless of whether any attempt is made to instantiate the template or not? This feels like a more general problem where bugs in templates remain unflagged by the compiler if the templated code is not used. It strikes me that if it's possible to address that, it might address the observed problem more robustly than just addressing how phobos consumes the errors. --
