[antlr-interest] book examples list

[Edwards, Waverly]

That is exactly what I am referring to.
I think if structural equivalence is done
you have more work to do but by name you
probably have to look up names and their
aliases.  Maybe and alias (typedef) might
not be considered equivalent.

Interesting stuff.

I believe Edwards means that one can have the following two structs:

struct A {
int i;
char c;
};

struct B {
int i;
char c;
};

struct A a;
struct B b;

Under name equivalency a and b can't be compared because they are of
different types, but under structural they can.
