--- Comment #13 from Marc Glisse <marc.glisse at normalesup dot org> 2011-06-04 09:31:40 UTC --- (In reply to comment #8) > Here, instantiating > std::pair<VectorH3<Kernel>> involves evaluating > noexcept(ploum<VectorH3<Kernel>>::value), Hello, I am far from a specialist. Is it necessary to evaluate the noexcept expression so early? It feels like it could lazily wait until something really looks at the swap function, but the standard may require that early evaluation. (clang currently rejects this code for the same reason) PR c++/49266 is another example of code that started failing to compile. I hope we will manage to avoid a situation where people reimplement their own pair/tuple to avoid the noexcept limitations...
