- You should try to make CARs and CDRs of them instead.

- : In what way is Lisp "bland ... all the way through"?
-
- There's little visual distinctiveness to distinguish mentally
- distinctive constructs.
-
- : How does Lisp's expressiveness (which I believe measures "easy to say
- : and understand") "[get] a big yawn"? Is it because Lisp is so expressive,
- : that it is boring?
-
- No, I'm saying that Lisp is only expressive by one rather cerebral kind
- of measurement, which neglects many human factors related to how we
- think, perceive and talk. And that this is the primary reason people
- avoid Lisp.
-
- : Are you saying that most other languages, because they are so
- : horrible and so inexpressive, are not boring because they elicit anger
- : and frustration, whereas Lisp does not elicit those emotions?
-
- I don't believe that the absence of boredom implies the presence of
- anger and frustration. All these states of being are in opposition to
- creative excitement.
-
- : Are you saying that you think that the true challenge in programming
- : is the actual struggling with the language, rather than the addressing
- : the deeper issues (such as, what it is you are trying to do)?
-
- I haven't noticed people struggling that much less with Lisp than with
- most other languages. Admittedly, nroff is a bit tougher, unless
- you're just trying to do text processing... :-)
-
- : In what way does Lisp "push down so hard" on morphology?
-
- One form to rule them all,
- One form to find them,
- One form to bring them all
- And in the darkness bind them.
- In the land of machinery, where the symbols lie.
-
- Essentially, Lisp assumes that humans like to write programs the same
- way the machines like to execute them, and so conflates the human
- representation with the machine representation. True, there are Lisp
- compilers, but the "ideal" is still that the machine and the programmer
- are interpreting the exact, same, one-size-fits-all data structure.
-
- : Where's the "tar pit", and what languages do better? (I can think of
- : some languages that do better in some areas, but none that, taken as a
- : whole, do better for most purposes).
-
- That's precisely the point. "Beware the Turing Tarpit, where
- everything is possible, and nothing is easy."
-
- That said, I should back off a little and admit that there are a few
- things that are easier in Lisp than in other languages. But your
- assumption seems to be that it's better to use an all-around mediocre
- language for most everything than to use each language for what it does
- best. I'm just pointing out the obvious fact that most people disagree
- with that assumption nowadays, and that I suspect that this is the
- answer to the question posed in the subject line of this thread.
-
- : I can't even decide if you are serious or not. I guess that all of
- : your handwaving means that you must be making a joke. In that case,
- : I guess I am too dense to get the joke.
-
- Never assume, just because I'm making a joke, that I'm not also quite serious.
