Vote++, though I'd venture to say the same thing about min(), max(), array(), and a few other misc goodies from std.array, std.algorithm, std.functional and std.range. This would make D a much better language for small/scripting programs, if you didn't have the friction of having to import all these small convenience functions.
Right now my solution is that I have a module called custom.phobos (custom is my very uncreative namespace for libs that I write that are not intended to be release quality and are just for personal use) that publicly imports all the Phobos modules that I use just about everywhere. std.all would have been a great idea, except it causes too many naming collisions and the need to use qualified names.
