Why not do:
in friend_selector.html
{{def selector(id=None):}}
<div class="friend_selector">
<div class="access_photos" users="[]"></div>
<input {{if id:}}id="{{=id}}"{{pass}}
name="access_input"
class="access_input" size="30" type="text" value="" />
</div>
{{return}}
and in the extending view {{include 'friend_selector.html'}}
{{selector(id='main-access')}}
This is already supported and allows to define more than one function
in include. And it is more pythonic.
