Perhaps the function shouldn't accept the unit of sec². Not least because I have no idea what a delay in that unit could signify.
const (
Nanosecond Duration = 1
Microsecond = 1000 * Nanosecond
Millisecond = 1000 * Microsecond
Second = 1000 * Millisecond
Minute = 60 * Second
Hour = 60 * Minute
) time.Second * time.Second
I agree, though, that this is not quite sound, because it can be misused, as shown above with `time.Sleep(delaySecs * time.Second)`.
In Kotlin you can do `1.seconds + 1.minutes` but not `1.seconds * 1.minutes` (compilation error), which I quite like. Here is a playground link: https://pl.kotl.in/YZLu97AY8
I know how to implement that in Haskell, and that it can be implemented in C++ and Rust. I know how to logically implement that in Java or Typescript, but usability will suck (no infix operators).
For a good example of what it looks like when somebody does bother to do it, see F# units of measure.
