Python too. I don't think you could put the whole program on one line,
because I don't think you can dedent except at the end of a line.

You can ask for it in most editors.

What's the extention for Haskell source files? Can you post a snippit of
Haskell here?

Out of curiousity, does elisp run outside of emacs? Can emacs run without a
window open? I.e., could you write a web server in elisp?

Uh, visual studio?

You should try an IDE that indents Python for you. It's really actually
fewer keystrokes than C-like languages, because the start-of-indent is part
of the syntax. There's an indent key and a dedent key, and you use them
*instead* of { and }.

Plus, as you're typing the arguments, it gives you help for each argument.
image.Draw(screen, []
and the drop-down list will say something like
float rotation
Amount to rotate the image in radians
I.e., so you know whether it's radians or degrees expected.
And this works for your own code. Even before you save the file.

Even though the C and C++ languages don't require any newlines to be
used, the C preprocessor does (you can't put two #-directives in one line).
If you avoid using preprocessor directives completely (which is completely
possible, although inconvenient) you could write any C or C++ program in one
single line (or at least I can't think of any exception right now).
Not that this is a good thing per se and all in itself. Just commenting.

Haskell really will allow you to put the entire program on line (really
long) line.
But then, in Haskell, whitespace is *optional*. You can use semicolons
and curly braces instead if you prefer. It's just that nobody ever does
(except for sticking several items on one line).

Really? Why on earth would you want to? Tabs are evil and should never
have existed in the first place! o_O

Plain source is *.hs, "literate Haskell" is *.lhs (That's where all text
is comments be default, and source is quoted, rather than the usual way
around.)

What, the other groups don't have enough Haskell source in them already?
qsort xs =
case xs of
[] -> []
[x] -> [x]
x:xs ->
let
ys1 = filter (x <) xs
ys2 = filter (x >) xs
in qsort ys1 ++ [x] ++ qsort ys2

No idea mate, no idea. :-)

As documented, VS doesn't indent things the way *I* like. ;-)

Or find out what the hell the order of the argument is...

I guess not. I figured you meant "indenting as you type" or something. Not
"strip all indicators of block structure, followed by trying to replace
them." The editors one uses for python all indent when you start a block
automatically and keep that indent until you type the dedent character.

Only if the software you're using strips them out on purpose.
What you're saying is "Python using whitespace is stupid because a lot of
web sites don't treat whitespace as significant." Sure, OK, that's an opinion.

Your cut and paste has to be smart about reindenting the code, yes. But
that's no harder than indenting code based on { } markers.

In emacs there's one single key for indenting, which will indent new lines
or existing lines, regardless of where in the line the cursor is at the
moment and whether the line is currently over-indented or under-indented.
How is that "fewer keystrokes".
> and you use them *instead* of { and }.
{ and } have nothing to do with indentation. They aren't even necessary
for all code blocks.

That's only *part* of it. Autoindentation works on existing lines too.

I think it's a very valid opinion taking into account the amount of
programming forums and blogs out there.
