[Bug] empty functions (or event handlers) are not allowed

[rozek]

it would surprise me if the following behaviour would be intended:

trying to define an empty function causes the parser to throw an error - just a comment as function body is not sufficient:

  def globalFunction ()
--    get $x
  end

throws the following error

_hyperscript.min.js:1 hyperscript errors were found on the following element: <script type=​"text/​hyperscript">​…​</script>​ 

 Expected commandList

--    get $x
                ^^

 Error: Expected commandList

--    get $x
                ^^

The same applies to event handlers
