Re: [Bug-apl] Implementing Dyalog Key function

[Juergen Sauermann]

Hi Elias, I am not quite in favour of it and it has problems. It is not on my keyboard (even though I am using a Dyalog keyboard). Not to talk about other keyboards. It does not really look like need-to-have function and I suppose it can be efficiently performed by a short combination of other APL primitives. In my opinion adding primitives for every imaginable use case (and there are certainly use cases for the key function) leads to an overloading of the APL language in the long run and does not improve the language. Another problem is that after reading the description several times, I still can't explain in simple terms what the function is actually doing.  That makes it a good candidate for a never used function if it should ever be implemented.

It's described in this article on the Dyalog site: https://www.dyalog.com/blog/2015/04/exploring-key/ Jürgen, are you in favour of this function? Regards, Elias
