You can write a library, but you're almost on your own. You can take 
advantage of D support for standard C runtime, but not C++ which is too 
clumnsy and not a target for D. We want something more elegant than C++.

I have here an implementation written for an ehanced C compiler 
supporting operator overloading, which is though incomplete, might give 
you an idea of how to do it if you like. It was written by the 
maintainer of LCC-Win32 and only works in it, should requiere a moderate 
amount of change and refractoring to work in D. HINT: you're not 
changing this libarary but writing a new one "inspired" by it and the 
original C++ iostream. :)

For you to get started: the library expects the main application to 
create the cout buffer. A buffer can either be a file, of a dynamic 
cstring. If you want it as a file, you open the file as usual and pass 
it to "iostream_new_from_file(FILE *)". In the case you want it to be a 
string, you use "iostream_new_from_string(char * buf, int length)". If 
you pass NULL as buf it shall allocate memory as requiered all by 
itself. Length limits the length, unless it is 0. This would be 
simplified in D.

Hope this can be helpful.
