It's just a matter of taste.  Personally, I usually prefer using many
($)s rather than combining (.)s and ($)s on the same "phrase".  For
example, I prefer

  foo =
    finish $
    doSomethingOther $
    doSomething $
    initialArg

to

  foo =
    finish .
    doSomethingOther .
    doSomething $
    initialArg

It gives me a feel of simmetry.  You may even align the $s, either on
the left or on the right.

But, like I said, it's just a matter of taste =).

Cheers,
