How about appender.put() with var args?

I guess chain could work in some cases, and are not that bad on 
the aesthetic side, I supposed. However having to include 
std.range just for that, and more importantly, all parameters 
having to be the same type, as opposed to just being "appendable".

Creating an array inline is also not an option as I generally 
don't like to trade aesthetics <=> efficiency.
