First lambda, formatter for StringJoiner?

I played around with the Java 8 early access build for the first time
last week. Overall it was fun and I learned a bit. One thing struck me
looking at the Collectors.toStringJoiner() method:
StringJoiner is pretty neat but it could use a formatter string, like
java.util.Formatter. It's a common pattern to need to format objects as
one collects them into a string. For example, a stream of bytes will
often need to be formatted as two character hexidecimal strings, rather
than the default decimal representation.
Adding a formatter string both to StringJoiner's ctor as well as to the
static convenience method in Collectors would be a big boon to Java
OK, that's my 2 cents! Good luck folks.
