So, you're saying that it's NOT a <pseudo>copy</pseudo> of the value of the
computation?

Suppose you assign with <dtml-let a sequence from a objectIds() method.
At a splitsecond after the <dtml-let has been assigned you remove all
objects that the objectIds() depend on in some other process (i.e. next
time, there will be no result left).
Will the <dtml-let have "saved a copy" or will it break?
