I'd just add that many of the APL example characters discussed in this thread have shown up as [square] on chrome webmail client... so unreadable even if I understood APL. ----- Original Message ----- From: Devon McCormick <[email protected]> To: J-programming forum <[email protected]> Cc: Sent: Friday, February 28, 2014 10:32:13 AM Subject: Re: [Jprogramming] apl character support Also, you're sacrificing some of the nice relations between some of the J symbols and making it less well-integrated if you throw in random APL characters. In the above cases, I'm thinking of the relationships between the variants of "power": ^ exponentiation, ^. log, ^: power conjunction. Working on extending J's capabilities in other areas makes much more sense than sprinkling APL characters into the language. Better integration of multi-processing, compilation of a subset of the language, better integration on the browser, more rosetta equivalences for different languages - all of these deserve more work. We need to make J more mainstream, not weirder. At the APL Moot two years ago, I pointed out that I could cut-and-paste Chinese characters into my emacs session from the web more successfully than I could do this with APL - some of the special APL characters show up as blobs.
