eliminate junk from std.string?

[Andrei Alexandrescu]

There's a lot of junk in std.string that should be gone. I'm trying to 
motivate myself to port some functions to different string widths and... 
it's not worth it.

What functions do you think we should remove from std.string? Let's make 
a string and then send them the way of the dino.


Thanks,

Andrei
