How to format function definition with arguments on multiple lines?

I'd like to put arguments on different lines, but I get parse errors on all the variations I try, including adding commas, allwin-style parens, and different indentations.

  constructor: (
    @a
    @b
    @c
  ) ->

Try:

constructor:\
( @a
, @b
, @c
) ->

Both trailing \ and leading , suppress newlines in CoffeeScript.

It appears you are out of luck. If you look at the grammar rules for the function definition, you will see that the rule is defined as:

'PARAM_START ParamList PARAM_END FuncGlyph Block'

The rule for Block allows for TERMINATOR tokens (which are semi-colon or carriage return) but the ParamList rule (the one you are interested in adding a new line in) does not allow for it.
