Unnamed functions, functors or, more formally, function literals

[Lars Brinkhoff]

This macro will return (something that is at least close to) an
anonymous function:

#define ANON(type, args, body) ({ type __anon__ args body; &__anon__; })

Example:

  printf ("%d\n", ANON (int, (int x), { return x + 2; }) (x));
