[Zope] using sequence variables

[Alexander Staubo]

Read through the DTML User's Guide.

Remember that

	<!--#var "something"-->

really means

	<!--#var expr="something"-->

and that

	<!--#var something-->

really means

	<!--#var name="something"-->

If you write something like <!--#var "sequence-item"-->, this is a
Python expression meaning "the value of the variable 'sequence' minus
the value of the variable 'item'". Instead, use:

	<!--#var expr="_['sequence-item']"-->

which extracts the variable from the namespace stack, just like

	<!--#var sequence-item-->

does.

"QED?" said Russell.
"It's Latin," said Morgan. "It means, So there you bastard."
