@ttamttam1 In my opinion the pattern is sound, for what amounts to pure functions I think it’s rather usable already. As noted in the report you can’t have the equivalent of side effects yet, i.e. computing a value and also manipulating config. Not sure when I will find time to figure that out, but I need this and will almost certainly eventually sit down and just do it. Contributions appreciated of course!
Also thanks for the reminder, added a license.
