Hi Sarah,

Yes. That's what I would like to do. It is actually very easy using a
filter for listOf<UnitDefinition> that accepts the first identical
UnitDefinition (using a call like
UnitDefinition.areIdentical(myJustDerivedUnit, unitNumberXXfromTheList),
with XX being the counter in the for-each loop).

Cheers
Andreas
