I understand that "#(fubar indeed!)" is reader syntax and doesn't affect internal representation of the lambdas. That was a comment to David that (as often happens in his posts) he is taking the literal meaning of metaphorical or elliptical expressions too seriously. Metaprogramming is the soul of Lisp, I know that and he knows that I know that. We disagree so violently because we disagree so little. ;-)[1] Re this sprinkling of bitter herbs: I just don't like the syntax (in general I'm not a fan of anatropic syntax in Lisp), and don't want to support use of it in the educational sense of support or in core maintenance in XEmacs. I don't expect to convince you, it's a matter of taste. My likes and dislikes matter to more than me because I do a *lot* of support, and the more magic there is in the world the harder it is to explain to users who believe in magic that under the hood it's just a lambda. I think this (car #(fubAr quux)) => 'lambda would be *very* surprising to most users. That kind of computation is what functions are for. Footnotes: [1] Not funny, actually, but I'm too old to change and respect David too much to ask him to change. I even kinda like him as he is. :-)
