The z in scalaz means this: it was early 2008 and I was working for a Java consultancy and so of course, I used the most appropriate tool for the job: scala. But it had *terrible* libraries, so I offered to fix those while also meeting my other objectives. Turns out that the Scala guys were extremely hostile to even half-decent libraries (and still are to this day). I still struggle to wrap my head around this sometimes.

Anyway, so I thought, well fuck it, I will just keep them to myself for now. My (awesome) employer had already agreed that we'd probably open-source such a thing, but I was concerned most about my primary goal. So then it came time to "name" this library. I had named it "scalax" simply so that I did not have the inclination to think of a proper name. Then I found out that such a library was being developed and with my internal name! Whatever, I thought.

So I looked at this scalax library, hoping that I could just abandon my efforts and jump on board with everyone else -- they too had figure

  // This character generator is similar to the default one from ScalaCheck, but it filters out:
  // 1. Unprintable control characters.  These cause problems in Mongo queries, and should not able
  //    to get into our database since they will not be present in inputs parsed from HTTP text.
  // 2. Characters that do not exist in the default platform encoding.  We can exclude a big range
  //    of these right away (which ScalaCheck does) because they're in the range used for two-
  //    character UTF-16 sequences, but others are only detected by checking Character.isDefined(_).
  //    The symptom of using a bad character in a string is that when you encode it to UTF-8 and
  //    back again, you get a different string, so any of our web and database tests that check the
  //    input against the output may fail-- and you'll see a question mark somewhere in the data,
  //    since that's how bad characters are displayed.
