I still don't understand why it is a nightmare to maintain the code.
For my C++ project, so far so good.

I can easily change filenames (that is class name or function name), I
can easily find them, I can easily move things around, all with just
the corresponding script command. I can navigate to the definition of
class and function by vim + ctags, I can see example code that calls
the class/function. Whenever I suspect there is a bug, I can easily go
to the right level of class/function in the directory hierarchy to
write a test case to trace down the bug without having to use gdb.

Would you please let me why it is a nightmare?
