You made me look how old Visual C++/Visual Studio is.

https://en.wikipedia.org/wiki/Microsoft_Visual_C%2B%2B says: 27 years old. Not too shabby :-)

You should add refactoring capabilities for the C++/C#/Java tools to the list of features, I wonder how the Lisp stuff compares.

Yeah, due to dynamic types is might do well than C++/C#/Java refactoring tools.

However the first refactoring tools appeared on Smalltalk, which is also a dynamic language, but it doesn't have macros and the image provides metadata that Lisps don't always have available.
