[Zope] variable assignment

[Charlie Reiman]

dtml-let almost certainly won't do what you want since it sounds like you
want the value outside of the dtml-in. This would require improper nesting.
Oh sure, improper nesting sounds like fun but it is illegal.

<dtml-in yadda>
<dtml-let foo=sequence-item>
</dtml-in>     <!-- boom -->
<dtml-var foo> <!-- you won't even get here. -->
</dtml-let>    <!-- or here for that matter -->

You can:

1) Use REQUEST.set as Andreas noted. Ugly but available everywhere.
2) Install dtml-set. Inexplicably never made part of zope proper but really
ought to be.

I'd suggest #2.
