1 year ago One: A new way to do units.
Essentially, copied straight from siunitx, pp. 8-10.
Define a list of recognised units (SI + others as needed). Define prefixes. Define postfixes. The end. Units are then created by assembling the constituent parts, rather than having to modify the unit_codes enumeration all the time.
*Units* *SI Prefixes* *Special* *Other units*

square_metre # m^2^
joule_cubed_per_lumen # J^3^ / lm
_henry_tothe(5.2) # H^5.2^
joule_per_mole_per_kelvin # J mol^-1^ K^-1^
per_square_angstrom # A^-2^
centi_metre_per_atto_day_squared # ???
