Comment (by SmileyChris):
Sure. The problem I was facing is that my tag needed to find a separate
node (generated by previously parsed tokens).
Currently, the parser creates a root nodelist when starts parsing the
tokens (`nodelist = self.create_nodelist()`) but there is no way to access
this nodelist because it is only a local variable.
By allowing this to be an instance variable it allows tags (which accept
the parser instance as one of the arguments) to inspect - and modify if
necessary - the nodelist created so far.
Specifically, my `{% repeatblock %}` tag was taking on the suggestion of
Malcolm regarding allowing a the contents of a block node to be used more
than once in an old discussion (which, in certain cases, would still be
useful)
