I mention C++ just as an example. Right now, I'm working with a few
different languages, C++, python, R. There might be other languages
that I will work with in the future.

Using existing refactoring tools might be a solution. But, I'm using
vim. A number of existing refactoring tools are integrated in Eclipse.
I heard a story that a group of programmers that worked closely
initially used different IDEs but eventually all converged to
vim/emacs and shell script, because these tools allows more
flexibility. Would you recommend me to learn to use Eclipse, if I want
to do refactoring for a number of languages?

Also, ctags can parse quite a number of languages, maybe it can be
used to help refactoring for various language.
