Here are some ideas to make the io sitution more obvious to people. Basically
follow what C++ does and move std.stdio to std.cstdio and make a std.cstream
that wraps a FILE* in a CFile (or something like that) and have
std.c.stdio.stdin/out/err wrappers. So there would be three "stdin" apis:
std.c.stdio.stdin, std.cstream.stdin and std.stream.stdin (plus the
platform-specific apis in std.c.windows.windows etc). Same goes for stdout and
stderr. The semantics of FILE* is slightly different than Stream so it could be
problematic replacing one with the other. D will differ from C++ in usage,
though, since std.cstdio will be used much more often than in C++ code.

ps - sorry if this post is sent twice - the one I sent earlier didn't seem to
come through.

a clarificatoin: since cstream would publically import std.cstdio the wrappers
of stdin and friends would have to have different names.

what about following:

   static:
      char[][] commandLine;

      istream   input;

and forget about std.c.stdio.stdin and other inhabitants of the zoo?

Isn't that just adding another animal to the zoo? The zoo in question is "how
many ways are there to print something to standard out"? I don't see how
self.input (or generally class.name) are much different than package.name -
fewer characters?

 Andrew.

some more names that come to mind:

std.cstream: wrappers around std.c.stdio
CFile cstdin, cstdout, cstderr

std.stream: wraps OS file api
File dstdin, dstdout, dstderr

I'm guessing that std.stdio will remain unchanged.
