I can't find a part of 14882 that deals with this issue--an oversight? Or am I blind? Does this need to get forwarded to the library issues list? > My inclination will be to get it into lidstc++ as an extension. Does > anyone have another idea ? Good idea. I say we either wrap this stuff with a suitable macro from bits/c++config.h, such as: // Use corrected code from the committee library group's issues list. #define _G_RESOLVE_LIB_DEFECTS 1 Or make some other (documented) macro guard to turn on and off this extension. I would like to have this functionality though, in some form. I would also like to do the relevant reading, so I'd appreciate any pointers. . . Thanks, Benjamin
