import somepackage

import will scan the compilation path for .lo files matching the package name. When it finds it, it will add all class and function declarations. It does not have to compile those files. This allows the header files and source files to be the same files (unlike C, C++, etc). The compiler may walk the import tree compiling every file, or it may simply use declarations from the import tree, whichever is decided at compilation time.
