Massimo mentions here<https://groups.google.com/d/msg/web2py/MaL-nJFcKDc/R-JZ5DQOIzkJ>that one optimization tip is to remove "remove un-necessary {{...}} from the layout". Can someone speak to this- is there a real performance hit to doing
<ul>
<li>{{=var1}}</li>
<li>{{=var2}}</li>
<li>{{=var3}}</li>
</ul>
versus this
{{=UL(
LI(var1),
LI(var2),
LI(var3)
)}}
