I'll go with Ted Dennison here, partly. I use _Type, and I often run
into hardware descriptions of the form "register x bits 1 .. 3 store
the command type", so the natural name for this object's type is
Command_Type_Type. I usually change the name to Command_Label_Type;
I'm more commited to _Type than to matching the hardware
documentation. That is bolstered by the fact that I have yet to find a
hardware manual with a clear, consistent naming convention, so I don't
mind "fixing" it.
