Using semicolon in coffeescript is good or bad practice?

Question

When I want to write a class in Coffeescript that provides a chain of methods, I often run into the problem of having one liner in principle, but then adding a row to actually return an instance for the chain.

So, instead of writing a simple setter, for example:

class myClass
    setProperty: (value) -> @property = value

I have to break it and do it like this:

class myClass
    setProperty: (value) ->
        @property = value
        @

In my eyes, this really reduces the readability and compactness of the code, especially if you have many setters and other self-evident single inserts.

So, I thought about doing it differently and again adding a semicolon to my code, for example:

class myClass
    setProperty: (value) -> @property = value; @

The compiled JavaScript is actually the same, but although it's pretty handy, it also feels a little messy to do it this way.

class myClass
    setProperty: (@property) -> @
