In principle, that's fine. However in practice there are things like
a. comments which do not exist in the AST
b. preprocessor commands that appear and disappear before ASTs are on the
scene
c. (most important) emacs doesnt really do a full-scale context free
grammar analysis does it?
So I guess I am asking: Emacs uses regular exps to fudge a semblance of
context free structure. How does it do this?
