Happily you can use curly braces in Haskell if you really want to. You have the choice between:

    do something 10
       b <- somethingElse
       something b

and

    do {
      something 10;
      b <- somethingElse;
      something b
    }

I've only ever seen the latter style very rarely though. I think it's also good for generating code so that you don't have to worry about whitespace and lining your generated code up properly.
