Here's a list of things I collected a conversation on partial. Personally I think using partial almost never has a benefit, while there are some downsides to using it. There are exceptional cases where partial has a benefit, e.g. if you want to "wrap" a multi-arity function or a function with an unknown amount of arguments.

Some reasons not to use partial:

Some people find it harder to find out what's happening*

Better stack traces from SCI (if your code runs through SCI)
Better performance in some cases (inlining / intrinsics)

Some people have asked for merch for my OSS projects (stickers, t-shirts). Here's a link to all the products:

So, here's the link for the bb / nbb / clj-kondo t-shirt: https://www.zazzle.com/babashka_nbb_clj_kondo_shirt-235586485787281777

Some of my conventions:

Create initial build.clj with neil add build :deps-deploy true and then tweak. Use vanilla tools.build for maximum control and better startup time.
Have bb directory with task code which you can require from bb.edn
bb dev launches the dev REPL
bb publish prepares repo for publish (e.g. by updating something and creating tag), pushes and CI takes over. The name publish originated from vsce publish here
Probably going forward: use release count rather than commit count (less complicated to deal with and smaller numbers are easier to remember)
For new projects: neil license add mit (or epl1 or so)
