Appendable Join.join(Appendable appendable, String delimiter, ... )

[GoogleCodeExporter]

Hi,

Since the Javadoc of the method says it returns "The same appendable instance 
that was passed 
in", I was wondering why the signature for the join methods was not something 
like:

public static <T extends Appendable> T join(T appendable, String delimiter, ...)

This signature ensures that the return type will be of the same type than the 
parameter.
This means that if I use a StringBuffer as input, I will get a StringBuffer as 
return value and not an 
Appendable (that need to be casted to StringBuffer :( ).

What do you think about that?

Hmm.  Why, I can't remember whether we ever thought about that or not!  We'll 
try it
out and I hope it works.  It works for Preconditions.checkNotNull, so...

thanks.
