>Ah, did you enjoy it? I'm headed there next month. Any tips? Sure, I always do (I go there several times a year). If you are interested in archeology and architecture then a day trip to Uxmal is a must (Mayan architects employed phi and other algebraic numbers in their designs). If you like scuba or free diving then you could enjoy the Great Mayan Reef (along the entire east Yucatan peninsula) and the cenotes (connected sinkholes in the jungle). If you are going to the next NYCJUG we can chat more about other options afterwards.

I'm not so worried about the credit, though I do like to see my name in print, like anyone else (except celebrities). I was wondering if anyone had realized strand notation was *possible* in J before I did, and if so I was interested to read the historical context and maybe find other new ideas. > Having said that, although I like to give credit when I can, > I think it is becoming more and more difficult to do so properly > because of recurrent themes and the number of contributors. Agreed, we are a very like-minded community. Also, the set of all short programs is smaller than the set of all long programs, so we're bound to see some repeats. > Incidentally, have you considered using the empty string > (‘’) as a marker since it is a neutral element under append. Interesting thought. It's possible already, using the script I linked [1]: '' 'Jose' 'Mario' 'Quintana' s'' +----+-----+--------+ |Jose|Mario|Quintana| +----+-----+--------+ Aesthetically, I like it. The double-single-quote ('') is reminiscent of double-quote ("), which acts nicely as a balanced marker, yet is a noun (and, as you say, append's neutral). > I know, I once mentioned to him that is was actually possible > for an adverb to take another adverb or a conjunction as an > argument and puff! It was gone. Yeah, I've lost some fun toys that way. And actually I remember you mentioning this. Do you have an actual expression that exploited this loophole in an earlier version of J? Or was it just theoretical (permitted by the DoJ, but not by the interpreter)? I would be excited to see that. > we could just start a very exclusive underground J club ;) I'm up for it, but we need a name.
