Extension: List Types


printlist(list(char*) *strings)
  list(char*) *l;
  for(l=strings; l; l=l->tl)
    printf("%s\n", l->hd);

Syntax & Semantics

A list structure is defined as:

struct list {
  void *hd;
  struct list *tl;

The extension defines a new type specifier list(T) where T is any valid pointer type. The implementation of list(T) is equivalent to the struct list shown above, but if T and T1 are different types, then list(T) and list(T1) are treated as different types for the purposes of type checking.

Probably the extension should implement more generic parameterized types.
