But using +/÷≢ to mean average isn't like using AddReduceDivideTally, it's like +/÷≢. With substantial array programming experience I do read this as a single word and pronounce it "average"; why should the fact that each symbol has its own meaning prevent me from processing them as a group? It's purely a benefit in that I can (more slowly) recognize something like +/÷⊢/⍤≢ as a variant of average, in this case to average each row of an array.

My opinion on the overall question, which I've written about at [0], is that it's very widely acknowledged that both symbols and words are useful in programming. This is why languages from PHP to Coq to PL/I all have built-in symbols for arithmetic, and usually a few other things, and built-in and user-defined words. The APL family adds symbols for array operations, and often function manipulation. Perhaps not for everyone, but, well, it's kind of weird to see a proof that a language I use to understand algorithms more deeply couldn't possibly do this!
