I can factually only report what is missing. Whether it can be added,
I don't know. As I just wrote in a few other messages: pointers,
unions, functions pointers, packed structs, incomplete/recursive
types. Also "flexible array members" (i.e. open-ended arrays).

While it may be possible to come up with a string syntax to describe
all these things (*), I wonder whether it should be done, and whether
NumArray can then support this extended data model.

Regards,
Martin

(*) perhaps with the exception of incomplete types: C needs forward
references in its own syntax.
