Although StrBuilder supports CharSequence (and thus StringBuilder), it does so by converting it to a String temporarily. This is a bit wasteful.

It would be useful to support StringBuilder directly, as that provides the getChars() method which does a direct copy of the buffer contents.

This would involve adding two new methods:

getChars(StringBuilder)
getChars(StringBuilder, int, int)

which can be a direct copy of the StringBuffer methods.

Sadly there is no accessible interface or super-class that would allow the methods to share code.
