Ah, I see this is an issue already discussed in length. Well hopefully 
something comes of these discussions.

Thanks for the links.

Probably, this is well feasible, but IMO, it would be really worthwhile
to - optionally - enable the usage of an external tool to do dependency
scanning, for new languages as well as for the premier ones like C/C++
in case one wants to overcome the built-in scanner's shortcomings while
accepting certain performance penalties. There has already been some
considerations and requests in this regard, e.g.:
