No tags on the class line. It's not a declaration either, it's another 
way to define a method named 'inspect' on the value of 'a'. 'a' must be 
a local variable.

Depends on the value of a. Which would be pretty hard for etags to 
track, hence my earlier suggestion to skip it:

     If it's followed by something other than "self"...
     maybe even skip the following scope altogether.
