This is really good, saved it to the memory bank, to try it out myself, quick google reveals it works because you have a fallback/default as last option which stands in for the 'false' part of the syntax. Very nice.

Is this a recursive function? It's cool.

Hello. Just to clarify what is being asked for, func. should return an array for each name with two entries, not an array with all entries of anything else right?
Sorry to ask, I have been tripped up a couple of times already not understanding precisely what is being asked for.

Thanks!
