Hello scala, my old friend
I've come to take you home again
Because a feature slowly creeping
left me plagued with doubts and weeping
and the version that was tagged in the repo
just has to go
it lacks the signs of soundness

On sleepless nights I hacked alone
applying ant and other tools of stone

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
