I don't know about Python. In Haskell, any file containing a single tab
character is immediately rejected (since tabs don't have any
standardised width). If you're coding in Haskell, you're just not
allowed to use tabs *at all*.

Actually it's pretty logical. You might argue that requiring the
programmer to manually type a semicolon at the end of each line when
it's obvious that each line is a seperate statement is illogical.

The only real problem with using whitespace is that it tends to get
mangled in emails, forum posts, etc. This isn't a problem when you're
writing programs. This is *only* a problem if you try to post code
snippets on forums and so forth. (And yes, it's kind of irritating.)

I have no idea how Python works. What I do know is that Haskell is quite
sensible about this. If you have, say, an if/then/else expression, you
can write it all on one line, or on three seperate lines, or maybe on
even more lines than that. Hell, if you want to, you can write an entire
Haskell program on one line; whitespace is *optional*, and you can use
it the way you want to use it, provided that a few simple rules are
followed. It's really not that difficult.

Depends. I don't know Python's syntax rules. Haskell uses whitespace,
and it should be possible to autoindent it. (I'm not aware of any editor
which does it, but then I'm not aware of any editor which knows what the
hell Haskell is...)

And to think that I do all my programming with an editor which doesn't
give me syntax hilighting *or* automatic indentation...
(Then again, I've yet to see an editor with auto-indent which actually
indents stuff the way that *I* want it to, rather than the way the guy
who wrote the editor wants it to.)
