Very pleased to have been of help! I love scala but Java really isn't too bad (streams API is fine except that you need to explicitly move in and out, rather than getting to do the cool scala thing of just using methods in the phenomenal collections library) and I don't like dunking on it, but it really does need a few helper libs. Tuples, either and try I think vavr has. Java seems to have covered most other stuff now. But been a half decade since I've written more than 10 lines at a time so hasn't come up for a while. Sorry. Reminiscing. Sunday night blues.
