As someone who has worked for years on a UI consuming such information: it's bloody difficult. Each language has its own weirdnesses, you almost always have to build the code to figure out the cross references, and what's correct to the compiler is often non-intuitive to the user. Prime example: C++ code mixing macros and templates. There isn't even a good definition of what the definition is!

I probably do underestimate its difficulty, but certainly appreciate it's bloody difficult. Hence I'd love someone else to do it! I don't have the appetite for it, but it would be fantastic to use.
