You declare static functions on a struct or class and then make 
the struct or class unusable as an object (e.g. by having a final 
abstract class or explicitly disabling all ways to construct the 
struct or class). There are at least a couple of places in Phobos 
that do that already (e.g. std.windows.registry.Registry and 
std.datetime.Clock both use final classes with an @disabled 
default constructor).
