332// A NOTE ON THE ORDER OF TRAVERSAL
333//
334// Types and typedefs have their base types visited before they are added to the type table. This is ok, since there is
335// no such thing as a recursive type or typedef.
336//
337// typedef struct { T *x; } T; // never allowed
338//
339// for structs/unions, it is possible to have recursion, so the decl should be added as if it's incomplete to begin, the
340// members are traversed, and then the complete type should be added (assuming the type is completed by this particular
341// declaration).
342//
343// struct T { struct T *x; }; // allowed
344//
345// It is important to add the complete type to the symbol table *after* the members/base has been traversed, since that
346// traversal may modify the definition of the type and these modifications should be visible when the symbol table is
347// queried later in this pass.
348//
