I think he meant that lambda's main use before was inside map and filter; as stated earlier in the thread, lambda's main use was for passing simple functions as arguments, and of these map and filter must have made up a majority (and then I'd guess TKinter would be next). List comprehensions replace map and filter, so... I wouldn't put it as explosively as he has, but I find a lambda less clear than a def too.
