Yes, but I was only looking at items labeled with Inject so my problem space was smaller. I have not tried to do a general purpose version so I don't have a 1:1 comparison with describeType which is obviously gathering a lot more. Extrapolating from what I did see, it is much more efficient than storing all of the metadata. My point on opting in was that in increase should we automatically use this method AND someone also still uses describeType at all. As far as storage, it was static data. Effectively, again my goal at the time being very single purpose, for each class that had Injection points it stored a reference to that Class as well as the properties and methods labeled with Injection in three arrays (one for constructor arguments, one for fields, one for methods). In my particular case, I would also recursively store the same information for classes referenced as types herein, meaning that if one of the constructor arguments was of type ClassA then I also recorded this same data as I was attempting to optimize recursive object graph builds.
