Just as others have noted, I'm worried about the intermediate representation hiding necessary details. Here's an example: If I'm looking at one of these classes that have been compile time injected with new functionality, is there an easy way to see what's been added without looking at these compile time injections? Specifically, it would be great if there was support for looking at both the source code before the injections and the source code after the injections in an easy way (built in IDE support for example). While different from what's being proposed here, C/C++ macros can be used for massive amounts of code generation, but looking behind the curtain of the macros involves running your source code through the preprocessor. Getting to the intermediate representation for macros feels tedious and most IDEs have limited support to aide the programmer pulling the veil off of macro code generation. I can imagine (*though maybe wrong) that a similar problem exists for certain types of template meta programming.
