Actually, we probably only /need/ printf(), and certainly for C programmers (are there any of us left? ;), I think that would be a small conceptual leap. The motivation for keeping a non-formatting version is for simple cases, and beginners -- both of which use cases should not be dismissed. The reason I proposed two versions is because I'd really dislike putting the format string in any position other than the first positional argument, and I can't think of a way to definitively distinguish between whether a first arg string is or is not a format string. One possible way out is to define a string literal that creates Template strings, and then make the Template string syntax rich enough to cover today's %-substitutions. Then if the first argument is a Template, you do printf()-like output otherwise you do print()-output. -Barry -------------- next part -------------- A non-text attachment was scrubbed...
