You can't do this with any of D's built-in introspection features 
(like `__traits`), because those features have no way of looking 
inside functions.

However, you can probably write a program to do this using the 
DMD frontend as a library.

Dub package (use the `dmd:frontend` subpackage): 
https://code.dlang.org/packages/dmd
Documentation: https://dlang.org/library/dmd/frontend.html

Unfortunately the documentation is somewhat incomplete, so you 
may need to spend some time reading the source code to figure out 
how it all works. Don't hesitate to ask if you have any questions.
