I think using a separate extension for C++ header/source files that have
to be preprocessed with MOC would have been a wise decision if it were
made from the outset. I don't think anyone ever regretted being able to
determine a file's type from its name.

I don't think there are a lot of tools like MOC, specifically:

1. MOC input is embedded into regular C++ files.

2. MOC output is required in order to compile said C++ files.

Well, they are certainly welcome here and I am very interested in having
a build system module for MOC.
