both implementations are actually the same, because #visit: looks like 
this:

	Visitor>>#visit: anObject
		anObject accept: self.

But you are right, the names of the messages in the visitor 
implementation of SmallWiki 1 are somehow strange and confusing. This 
will be improved in SmallWiki 2. Have a look  at past posts in the 
SmallWiki mailing-list that discuss that issue.

Most of the time this isn't necessary: you could put an inst-var into 
your visitor class, remembering the parent of your links.

Hope this helps,
