What editor do you use?  If you use a relatively smart one (e.g. vim,
emacs etc), you should be able to configure it to do it to do what you
want when the extension is .hs or .lhs or whatever.

I use vim and I have been known to use the following:

	set ts=8
	set sts=4	" Or sometimes 2

With either expandtab or noexpandtab as the mood takes me.  That way,
when I hit "tab" I get 2 or 4 spaces, which are expanded to an 8-space
tab if I hit it enough times.

The language does not force you to do anything of the sort.  It's your
editor's fault if it can't decouple the concept of hitting the tab
key from the concept of putting a ^I character in your file.
