The Unit type exists for the cases where you want a type-safe equivalent of
undefined or null. It's a concrete instance, which won't blow up on you,
and you can safely use it with e.g. Result without being concerned that
you'll accidentally introduce null or undefined back into your
application.
Equivalent to () or "unit" in many functional or functional-influenced
languages.
