I don't see that is possible because refactoring (or any other code wizards)
for the language requires knowledge about the language. For example,
an algorythm of adding a class method is different for different languages.
That's why each language support plugin have its own parsing code.
Nevertheless, we have "Code model" - a least common denominator of code
structure that is used by other plugins to perform various operations on
code symbols (example is a class viewer which uses code model to represent
a tree of classes/methods/etc). But it is not possible to do refactoring
using only a code model because code model is not able to write changes
to source files. You need to write a change to a file and then update code
model to reflet changes. That's how code model works.
