Nodes: Comments lost when they precede an Existence operation where the first element is a property of this #4756
Description
Please consider
( foo ) ->
### Lorem ipsum ###
return ( @foo ? 42 )
( foo ) ->
### Lorem ipsum ###
return ( @foo )
( foo ) ->
### Lorem ipsum ###
return ( foo ? 42 )Of these 3 variations, the first one fails to preserve its inline ### comment.
(function(foo) {
var ref;
return (ref = this.foo) != null ? ref : 42;
});
(function(foo) {
/* Lorem ipsum */
return this.foo;
});
(function(foo) {
/* Lorem ipsum */
return foo != null ? foo : 42;
});One can see this on coffeescript.org
This phenomenon is stripping the jshint inline configuration directives placed there for use with coffee-jshint.
