I tried to keep the syntax as simple as possible. However there were  
several requests lately for that kind of things. I don't really know,  
how we could implement that the simplest without bloating the wiki- 
syntax and while keeping the visitors small that transform the AST  
into different output-formats (HTML, Text, Latex, etc).

The best idea I cam up so far is to add some sort of XML-Tags that  
can be parsed in a generic fashion, so that extensions can register  
their own tags. Something along ...

<pier:indented>
The time is now: <pier:smalltalk>Time now</pier:smalltalk>
</pier:indented>

Would that help? Is something like that of generic interest?

The scanner and parser is automatically generated from the respective  
definitions using SmaCC, so you probably don't want to change these  
methods manually ;-)

If you only want to do some simple string transformations when  
generating HTML you could simply patch the methods from the protocol  
#visiting-document in the class PRViewRenderer.

Cheers,
Lukas
