generally speaking ...

- code generation
- intercept calls in restricted environments and assert correct module names
  to detect possible
- diagrams generation
- models extraction
- data mining (relationships | dependencies)

generally speaking ... if talking of unittest plugin to load live
objects that's another situation.

However, suppose I'm developing some apps (each one under top-level
folder in VCS) adding unittest plugins and I want to develop a Trac
plugin (macro ?) that will know the path to top-level folder in VCS
and will look for unittest metadata definition inside setup.* (or
wherever it might be defined ...) of all direct descendants (i.e.
folders). With this data it will render inside a floating div some
links to Trac repository browser area (e.g. highlighting the lines
where the plugin code is located) . That would allow me to quickly
find plugin code inside e.g. repository browser and wiki pages (/me
the lazy dev ) .

example above ... and the *dot* notation would be a PITA, AFAICS .
