--- Comment #40 from Antony Polukhin <antoshkka at gmail dot com> --- > That doesn't mean it has to be fast though. Indeed. Alas, people write sub-optimal code, especially when pressed for time or when compatibility with old versions of the C++ standard is required. It would be nice to have those cases optimized if they do not add maintenance burden for GCC.
