Let: allows read-only variables to be computed whose values are usable
within a DTML nesting scope.

Local: allows writable variables to be computed, whose values are usable
and changeable within a DTML nesting scope.

Set: singleton tag that changes the value of a "local" variable, as long as
it was defined in the innermost surrounding "local" block.
