I think we need to show some multi-line/complex examples:
````
GOOD:
hash = { 
  1980 => "eighties",
  1990 => "nineties",
  2000 => "naughties" 
}
hash = Invoice.create({
 1980 => "eighties",
 1990 => "nineties", 
 2000 => "naughties" 
})

BAD:
hash = Invoice.create({ 1980 => "eighties", 1990 => "nineties", 2000 => "naughties" })
hash = Invoice.create({ 1980 => "eighties",
                        1990 => "nineties",
                        2000 => "naughties" })
