[Zope] change variable

[Charlie Reiman]

Uh, dtml-let is NOT equivalent to REQUEST.set. This is not an either/or
decision here. dtml-let is a namespace operator, much like Lisp's (let ...)
operator. Unforunately, most people assume let is like BASIC's let, which is
assignment, not namespace creation.

To put it another way, DTML does not prevent you from assigning values to
variables, but it does nothing to make it easy (like providing syntax). I've
always wondered if there was a design decision behind this or just a simple
oversight.
