I agree with Ralph and the original poster, but there is one
additional point about computer languages: they are still, like in the
1950's, plain textual files. Of course, every language has its syntax
and semantics, but we still are using editors, and more importantly,
the model of sources files, conceptually the same as punched card
I really think it is a pity that no language offers a fancier
interface than plain textual files, typed thru an editor. The syntax
directed editors of the late 1980's are gone.
It is a pity that no [major] programming language accept HTML pages
(or even .doc documents,...), or even provide its own fancy editor. In
particular, integrating some ideas from the literate programming
movement inside programming languages is not done. Comments are still
simple sequence of characters (perhaps with a specific markup like in
javadoc or ocamldoc). Our program sources are not hypertextual (even
if a few research papers mention this).
I think that is is mostly a chicken & egg issue: no languages is
non-plain-textual because no editor is able to edit them, and vice
versa. (and also, major editors like emacs offer sufficient "modes"
for programming languages).
Perhaps also researching on newer forms (hypertexts, fancy editors) of
source program is not fancy enough for academics (or for funding). I
still find it a pity.
I'm dreaming of a major [opensource preferably] fancy (perhaps
functional) language with a better editing mode than Emacs. I'll
probably dream for a long while!
