Why is my system slow? $ grep -R "map" * reduce(filter even? (apply ( 3) (map inc (i for i in (filter even? collection)))))* What's with the dissing on map?

Why is my system slow? $ grep -R "map" * reduce(filter even? (apply ( 3) (map inc (i for i in (filter even? collection)))))* What's with the dissing on map? Awkward code like that can be written in lots of ways... (rewrite it with transducers, friend catfish, rewrite it with transducers!)

<3 Searching "map" was an entry into the larger joke, but not sure if it came across on the psuedocode.

  Was it a 'functional programmers know the value of everything and the cost of nothing' kind of joke?

    It filters for even. Increments each element to odd. Multiplies each number by 3 (each number is still odd) Filters for evens then sums them. Always returns zero.

if I read this correctly, the reduce statement here is reducing an always-empty collection.
