--- Comment #2 from Net Can <netcan1996 at gmail dot com> --- (In reply to Iain Sandoe from comment #1) > There was a long discussion about this between the various WG21 paper > authors. > > The stated intend was that 'this' pointer and the 'lambda object pointer' > were intended to be cast to references (to the same type as their pointers). > > This behaviour should be the same between MSVC, clang and GCC (but I fear > that the amendment did not make C++20 timescale - so we might need a > coordinated change to remove it from the compilers). > > Does that explain what you are seeing? yes, I see. thank you for your explanation.
