nim does not support multiple inheritance (version<=1.4.6). It is just a demonstration of the procedure reloading nature of nim code.
<lang nim>type
Camera = ref object of RootObj
MobilePhone = ref object of RootObj
CameraPhone = object
camera: Camera
phone: MobilePhone
proc `is`(cp: CameraPhone, t: typedesc): bool =
for field in cp.fields():
if field of t:
return true
var cp: CameraPhone
echo(cp is Camera)
echo(cp is MobilePhone)</lang>
