G'day all.
Quoting Christian Maeder <[EMAIL PROTECTED]>:

But they're _not_ similar!
Compare this notation:
f . g . h $ x
with the one you suggested:
f $ g $ h $ x
Advantages of the first one:
- Encourages the idea that there is function composition going on.
Function composition is one of the features of functional
programming, so this should be highly encouraged.
- Protects your code against the day when the committee realises that
($) has the wrong associativity. (It's the opposite of what you'd
expect, since normal function application is left-associative.)
Disadvantages:
- None whatsoever. It's just as succinct and uses just as many
parentheses.
Cheers,
