Hello,

write and writeln just write; writef and writefln first format: seems clear. But the latter do not work properly with D strings, and the former do not work without format. Is there a practical way to just write anything to the terminal (without caring of its type)?

Is there some rationale about this?
Would it be possible to automatically add \0 to D strings passed to write/writeln (can a programmer define a custom func doing this before delegating to builtin funcs, or is it necessarily a job for the compiler?)?
And/or what about having writef/writefln use "%s" as default format (when the first arg is not a string)?

I don't understand what you mean.  This works just fine:

  import std.stdio;

  void main()
  {
      string s = "Hello world!";
      writeln(s);
  }

If I'm misunderstanding you, please explain, or perhaps give a code example.

Sorry, seems I just mistake the various C & D ways of coping with strings (too many forms of char arrays and functions that deal with them). I'll just stick with D funcs.
