[Zope] DTML: fetch an object by its url?

[Scott Shepherd]

In DTML is it possible to get an object using its url? Something like

    <dtml-with "get_object( '/some/local/url' )">...</dtml-with>

Similar to

    <dtml-with "_.getitem( name )">...</dtml-with>

but what I have is the object's zserver url, not its name in the 
current namespace.

TIA,
Scott
