Not easy on my eyes or brain :)

Oh I agree. I was just trying to make sense of [.{}] in understandable
terms because I currently just don't understand it :-)
But perhaps the reduce operator is some of that sufficiently advanced
technology that "knows" how the operator it wraps is slotted and does
something appropriate.
Also, does the reduction operator have the same magic as its alphabetic
twin such that it can pull N things at a time from the list for
operators that require N operands?
