<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Sadly erlang doesn't allow a trailing comma in the last element like<br>
<br>
[<br>
#haha{v=1},<br>
#haha{v=2},<br>
#haha{v=3},<br>
].<br>
<br>
otherwise, always trailing with a comma is a common best practise,<br>
e.g. in PHP arrays. When it becomes habit it's hardly a problem.<br>

Since this can silently cause bugs, the warning suggested in<br>
