@GlenO Thanks so much as always! I had initially tried ==[] and it was giving me errors but I tried again now and it's working. I must have messed something up before. ¯\_(ツ)_/¯ The only suggestion I couldn't use is getting rid of first; in this case I have to use first because x is an iterator/collection/something that doesn't have getindex defined.

Also, I could be mistaken, but if x is an array, then rather than first(x), just use x[].

At a glance, I see a few ways to improve this (just based on basic golfing). Use foldl rather than reduce (they do the same thing, but foldl has defined order and is one byte shorter). Use a direct comparison with an empty structure instead of isempty (I'm not 100% sure what type x is, but if it's a set, for instance, use x==[]). And use (q=join(p)) and then just q in the filter to save two more bytes.
