This thread is for discussions and opinions about the C++11 migration. The ticket (2669) should be used for documenting facts, decisions and tasks. My personal opinion is that we should make the move now. Because it's just a matter of time, most of the contra arguments don't really matter. It's better to get used to the new coding style early. Also I'd like to continue with my work on SpiderMonkey and not doing the migration would interrupt that abruptly. I'm not happy that a third party library puts pressure on us this way, but it's a question of what alternatives we have. Staying on V24 would be bad and switching to another scripting engine or even another script language like Lua has been discussed and discarded before.
