Yes, I usually have a few other macros that I use in code I write,
namely bitsizeof, fieldsizeof, fieldtypeof and a couple other, and all
are lowercased because:
  - it's a safe macro (doesn't multi-evaluate its arguments), hence the
    user doesn't really need to know it's a macro ;
  - similarity with sizeof().
