// Structs
// -------
// For structs, a combination is needed to define the type of struct
// IS   = Struct (Empty or incomplete, neither primitive nor complex)
// PS   = Primitive struct (struct containing only primitive types)
// CS   = Complex struct (struct containing other structs and primitive)
// NPS  = Nested primitive struct


// Some Possible combinations
// ==========================
//
// _IS   = incomplete struct without a typedef (forward decl)
// IS    = incomplete struct
// AIS   = alias of an incomplete struct

// (aliased) struct [ primitive | complex ]
// ----------------------------------------
// _PS  = primitive struct without a an alias
// PS   = primitive struct
// APS  = Alias of primitive struct
// _CS  = complex struct without a an alias
// CS   = complex struct
// ACS  = alias of a complex struct
// _CCS = complex complex struct without an alias
// CCS  = complex complex struct
// ACCS = alias of a complex complex struct
//
// Nested structs
// --------------
// there is always a hosting struct and a nesting struct
// in case of double nesting it can be both
//
// simply nested struct [ primitive | complex ]
// --------------------------------------------
// (aliased) hosting struct (complex always)
// _HS   = hosting struct without an alias
// HS    = hosting struct
// AHS   = alias of a hosting struct
// _NPS  = nested primitive struct without an alias
// _NCS  = nested complex struct without an alias
//
// doubly nested struct (complex always)
// -------------------------------------
// _HHS  = hosting hosting struct without an alias
// HHS   = hosting hosting struct
// AHHS  = alias of a hosting hosting struct
// _NHS  = nested hosting struct
// _NNPS = nested nested struct
// _NNCS = nested nested complex struct

// enums in structs
