digitalmars.D - Module imports

Hello everyone,
I would like to know how compiled modules actually work in D. The object files
usually store only implementation, but not the interface part. How is the
interface information being retreaved when a module gets imported? Does the
compiler need the source code of that module to parse the inteface data from it?
The phobos library seems to work fine even without the source code. Or do the
compiled object files get some sort of "manifests"?

Thanks!

They serve dual roles in D as interface, implementation and both.

The D compiler must have a source file when you import.  You can write a 
'stripped' D file which only has the interface, which when compiled 
using the obj/o file from your 'full' version of the D file will produce 
an executable.  Of course the 'full' version of the source file will 
work in all cases.
