Yeah, I end up with a family of asPercent convenience properties as well.

I haven’t really cogitated on it, but I tend to feel that some simple methods would have been much easier (for humans and the compiler) than the existing, complex design. e.g. asPercent(…) with just all the relevant parameters as actual method parameters, all in one place, easy to auto-complete, hard to get lost in.

That could also be added through extensions, I just haven’t happened to get that far yet – most of my uses are fairly specific, so I haven’t been compelled to generalise.

My ideal would be like:

Text(progress.percent())
