[Zope] is there a dtml-with convenience tag ?? or equivalent syntax

[Trevor Toenjes]

Is there a one liner that looks something like this?
  <dtml-call "foo.bar(something)">   **see below
        ed.-please dont take offense to my simple thinking

I am constantly writing "<dtml-with foo><dtml-var bar></dtml-with>"
just to get one(1) method from an object.

As I am getting into content categories using zClasses, I am now writing
many...
**<dtml-with foo>            --usually the category/folder with zClasses
    <dtml-with bar>          --the specific zClass
      <dtml-var something>   --the method to execute from the specific
zclass
    </dtml-with>
  </dtml-with>

I am searching for a simpler way to do this...

Thanks for feedback,  (or reality)
Trevor
