fills are a core part of the language or working with arrays. Being able to fill with _ is very convenient if 0 is a normal data item that needs to be distinguished from. Always Be Boxing avoids these issues, and so I can just keep on Always Be Boxing...
Maybe there is a way to invoke # (copy) in such a way that it creates fills, but its not clear how !. was meant to apply to it in the first place. ----- Original Message ----- From: Raul Miller <[email protected]> To: Programming forum <[email protected]> Cc: Sent: Thursday, August 28, 2014 6:28:46 PM Subject: Re: [Jprogramming] fit conjunction I guess the issue here is: what problem would this solve? (There's a generic problem with solving tautological problems. So it's good to have some larger situation in mind, to avoid cluttering up the language with overspecialized forms of generality.)
