Length.squared and Length.cubed are ambiguous APIs

"3 meters squared" -- is this 9m² or 3m²?

[sargunv]

Imo the following is intuitive enough that .squared and .cubed aren't necessary:

val length = 3.meters
val area = length * length
val volume = length * length * length // or area * length

and then, for units:

val area = 9.squareMeters
val volume = 27.kiloliters

I like the suggestion to go with

val area = 1.square[Unit]
val volune = 1.cubic[Unit]

The original motivation for squared and cubed was to avoid complex unicode characters in source code. Eg.

val area = 1.meters²
