Well, *ManagedStruct is already working pretty well. It is used to interface with C code that returns or takes structures of some natural types. It supports nested structures and pointers to these as well as arrays of items and a limited set of callback functions. See e.g. runtime/parrot/library/SDL* for a lot of such usage. Constructing such a struct takes a list of triples: - data type - optional array count of item - optional offset Alignment is calculated automatically, if offset is zero. Access to structure items is by index or by name, if the initializer list provides named items. Under the hood an exact image of the C structure is created. > Larry leo
