<dtml-let mydict="externalMethod()">
<dtml-var "mydict['key1']">
</dtml-let>
i know dtml will cache results on the same method call in a single
request which generally makes it efficient to do stuff like
<dtml-if expensiveQuery>
<dtml-var expensiveQuery>
<dtml-else>
cheap skate;)
</dtml-if>
and i'm guessing the same should apply to external methods.
