You can currently get the same effect by using extern keyword for c
functions in an included c file (you can pass a .c file to valac for
this purpose) 

The disadvantage to inlining is it destroys the platform independence -
IE you would not be able to create a gcc front end for vala nor would
you be able to have vala->c++ or vala->jvm/clr.
