I will second marks comment.
I often use variable=nul to indicate I will not be using the the result
within the list, for example when using list to determine when something is
displayed, and especially if inside the list I want access to
currentTiddler (the containing tiddler), particularly in the view template.
As soon as I decide to make use of the variable within the list I give it a
name that represents what it is that is being listed. Thus returning to my
code later I always see if I use nul that I do not care about the value, if
I see no variable I am using currentTiddler (Equivalent to
variable=currentTiddler) and if I use a named variable (other than nul) the
name reflects what in fact the list is doing/listing eg;
variable=closed-task.
The same variable name can be used inside a list but its value only changes
within that list, once the list is closed the variable will return to its
original value.

Tony
