[Swift-devel] New syntax for appending to arrays

Yes, where ? is the thread prefix id. (usually this is just 0,1,2.. )

Right now, a+= b works. += or APPEND is an improvisation over
the usual ASSIGN. So everything that is meaningful to the compiler
in ASSIGN works here as well.

The question of whether this is supposed to work, I don't really know.
