... or units of measure

This is a surprising gap for most non-ML type systems from what I’ve gathered. I don’t understand the gap, tbh. Most of us aren’t slinging primitive values with no particular domain in mind, it’s weird that we have to encode most of the domain in naming conventions and docs.
while I like it, it doesn't actually seem that useful.... and given I work on IoT systems measuring all kinds of things in all kinds of units, it isn't at all useful for that. Kind of cool for when you are using F# as a calculator though
I haven't found them useful in my experience either, but they seem to have a real indispensable utility in some cases like algebra for simulations. At least, that is what I gathered from Matthew Crews who has the "FastFSharp" channel on YouTube and a Twitter account with the same name. (He employs mutability heavily for performance, so not what I think of as an average F# developer.)
