Do you already have ideas how this should look like?

The first thing i thought about would look like that:
[sourcemode languagename
[rule name [regex] markup]
[rule name [regex]]
[rule [regex]]
[rule [regex] markup]
]

Where name regex and markup are only placeholders. name should be
unique within the block. The names should allow refering to other rules
within regular expressions. Quickbook should combine all rules in the
order given to a big alternative, and add a catch all parser at the
end.

Now I wonder if I should use xpressive, or spirit with regex.

PS: With that extensions one cannot implement quickbook within quickbook.

Andreas
