You could actually automate that as well, all your functions are defined
with a function definition, you would build a table of functions and then
traverse the code searching for these functions. Chances are you would have
the majority of functions traced. This leaves out dynamic functions, eval
and some magic methods, dynamic functions and eval are not the best of ideas
to begin with, though i admit, i have had to use them before. But it's not
to say that this would be impossible to solve. There are other ways to do
this too which would be a bit more involved...
