There's been talk here before about deprecating and replacing std.stream. I've found some annoying corner case bugs in it and also find it rather annoying that it doesn't work right with things like ranges and immutable strings.  Should I file bug reports and patches for some of this stuff, or is std.stream likely to be deprecated and replaced soon enough that it's not worth my time?

Also, I'd like some opinions.  Ideally, in the long run, should std.stream be cleaned up and made to work with ranges, immutable strings, etc., or scrapped and replaced entirely?  If the answer is the former, I might start working on it because it's near the top of my list of personal gripes that I think I know how to fix.
