Can enum class be nested?

Question

Can this be done?

enum A
{
    enum B
    {
        SOMETHING1,
        SOMETHING2
    };

    enum C
    {
        SOMETHING3,
        SOMETHING4
    };
};

No, there is no way of doing this without defining everything in a long list inside one enum.

enum class A{
  PARTICLE_MATTER_BARYON_PROTON,
  PARTICLE_MATTER_BARYON_NEUTRON,
  PARTICLE_ANTIMATTER_BARYON_PROTON // etc
};

If this doesn't make sense to you, then you are surely a physicist.
