- eru 16y agoIn Scheme try and compare (car (list 1 2 3 4)) with (car (lambda (x) x)) But I guess we are talking about different levels of abstraction?
- dexen 16y agoIndeed, you are right about Scheme (and Arc). Thanks for the correction.
- eru 16y agoSure, no problem. I guess Emacs Lisp falls under the old-and-broken category. And Picolisp eschews functions as a data-type by choice. Do you know whether Picolisp offers lexical scoping?
- akkartik 16y agoIt offers something similar-but-not-quite called transient symbols: http://www.software-lab.de/doc/faq.html#problems http://www.software-lab.de/doc/faq.html#problems Alternative phrases for similar-but-not-quite: insidious, error-prone.
- dexen 16y agoAs the other response says. The FAQ provides some rationale & makes it clear you can, actually, build robust software with picolisp's model of scoping. My understanding is, ``dynamic scoping is faster for an interpreter'' and ``funarg is easy to avoid and closures are possible''. See the three following points: http://www.software-lab.de/doc/faq.html#dynamic http://www.software-lab.de/doc/faq.html#dynamic http://www.software-lab.de/doc/faq.html#problems http://www.software-lab.de/doc/faq.html#problems http://www.software-lab.de/doc/faq.html#closures http://www.software-lab.de/doc/faq.html#closures
- amttc 16y agoNot that this has too much to do with what you two were talking about, but (car '(lambda (x) x)) will return lambda in Scheme.
- eru 16y agoYou are right. Actually I was almost going to add (car '(lambda (x) x)) to my post in the first place; in line with `The syntax for functions is lists.'
