Ok, I'll try again: let's suppose an extension that highlights chunks of
code that might have side effects, or that could use multi-threading
features, or that could result on calls to certain functions, or some
other condition specified by the user. There is no doubt about the value
of such extension, and it is technically possible. How could you do that
without accessing the full AST?
