It's not so cool, in my opinion. And indent paragraph tag would belong to
visual formatting. If you start using tags, why wouldn't you use them to
denote the logical structure of the program like the { ; } syntax does?
Obviously, the approach of denoting structure via indentation was used for
Haskell only because indenting is what most programmers use anyway when they
have some kind of substructure. You don't need any extra markup, you just
denote structure by using an obvious, nice-looking indentation style.
If you would use indent paragraph tags and look at the source code, this
source code wouldn't look very nice anymore. You could argue that you use a
special editing tool. But then you could use the logical markup I talked
about above and the editing tool would do the indentation on the basis of the
structure.
