CoffeeScript's interesting line continuation behavior

gistfile1.coffee

# all on one long line works:
if not foo or not bar or not baz = Some.reallyLongMethodName foo, bar, _
    error = true

# newline with matched three-space indentation level works:
if not foo or not bar or
   not baz = Some.reallyLongMethodName foo, bar, _
    error = true

# but newline with one regular indentation level *doesn't* work:
if not foo or not bar or
    not baz = Some.reallyLongMethodName foo, bar, _
    error = true

# interestingly, even using parentheses doesn't work:
if (not foo or not bar or
    not baz = Some.reallyLongMethodName foo, bar, _)
    error = true

# but newline with *two* regular indentation levels *does* work:
if not foo or not bar or
        not baz = Some.reallyLongMethodName foo, bar, _
    error = true
