Just to be on record, i am OK with adding a new way to do this as long as the old C style str format does not ever go away. I don't like 20 ways to do the same thing, but i really like the compact way of %formating now. My complaint is the deprecation of %formating. Maybe i'll use the new syntax to print a tuple or two, but that is the only use i have for it ;).
Slowing down Python even more than it is, is suicide. Sure high level languages are slower than there complied brethren, but a line has to be drawn in the sand somewhere. As CPU speeds increase so does the complexity's of modern software. GUI toolkits hog more resources as they need eye pleasing "glass effects". You can't just blindly Parrot off.. "well CPU's get faster every year". Python must stay fast, and simplistic(but not too simplistic), to compete with other high level languages. -- http://mail.python.org/mailman/listinfo/python-list
