Adding to RodgerTheGreat's comment: for me, k's power is its rich set of adverbs that are convenient to write. Notice that aside from reverse (monadic |), all verb symbols in the above code are in most other languages (max as |, min as &, plus as +, minus as -). Adverbs (such as / for reduce and \ for scan-reduce) make the symbols we already have more generally applicable. I think a language could go a long way with a small set of basic arithmetic symbols alongside a rich set of adverb symbols.
