Lost comment

[javysun]

In the begining

a.b/*This comment will be lost*/.c = /*bbb*/ function() {
    /*ccc*/
    alert(1);
};

After parse

a.b.c = /*bbb*/ function() {
    /*ccc*/
    alert(1);
};

Related issue: #754

Could be solved by introducing a comments_after property on the parse token that would work much like comments_before already does:
