Programmers who are human get tired of typing and seeing "(lambda" as an indication of an anonymous function. They wish that something shorter
like "(fn" could be used. However, disciples of CL are willing and eager
to make it even longer by putting "(functon" in front of it---despite
the fact that doing so is a pleonasm; "lambda" is a macro that expands
to "(function (lambda".
CL lickspittles always try to make their code as ugly and bloated as possible.
Daniel Weinreb, 24 Feb 2003:
Having separate "value cells" and "function cells" (to use the "street language" way of saying it) was one of the most unfortunate issues. We
did not want to break pre-existing programs that had a global variable
named "foo" and a global function named "foo" that were distinct. We at Symbolics were forced to insist on this, in the face of everyone's
knowing that it was not what we would have done absent compatibility constraints. It's hard for me to remember all the specific things like
this, but if we had had fewer compatibility issues, I think it would
have come out looking more like Scheme in general.
Jeffrey M. Jacobs:
The CL effort resembles a bunch of spoiled children,
each insisting "include my feature or I'll pull out, and then we'll all
go down the tubes". Everybody had vested interests, both financial and emotional.
Jeffrey M. Jacobs:
CL is a nightmare; it has effectively killed LISP development in this country. It is not commercially viable and has virtually no future
outside of the traditional academic/defense/research arena.
Bernard Lang:
Common Lisp did kill Lisp. Period. (just languages take a long time
dying ...) It is to Lisp what C++ is to C. A monstrosity that totally ignores the basics of language design, simplicity and orthogonality to
begin with.
Well, I'd say Scheme and CL are both today equally bloated.
Scheme looks minimal, but the truth is that in order to be usable, you
depend on tons of modules.
