[racket] status of keyword argument support in TR?

What's the status of keyword argument support in Typed Racket?

I found the below message from three months ago, after my Racket blew up 
in the same way:

I'll have to find a way to work around this or postpone my TR adoption, 
since I use keyword arguments heavily.
