Does anyone recall why modules aren't supported on Windows

macOS uses dynlib IIUC ?

Is there any value in exploring use of libclang ? It gives us a real
C parser that we can use to extract information from the C source. In
libvirt we have experimental patches (not yet merged) using libclang to
auto-generate XML parser helpers from struct annotations. It is quite
nice compared to any other hacks for extracting information from C
source files without using a proper parser. libclang can be accessed
from Python3 via its bindings and IIUC should be usable on all our
build platforms
Regards,
Daniel
