Subject: accessing structs defined in eval.c in extension


....yeah, I'm trying to do something wierd...

First off, why is there an eval.c that has several structs defined that 
would probably be better to have defined in an eval.h file?  (but there is 
no eval.h file)

I'm trying to access a member of the BLOCK structure that is defined in 
eval.c in an extension.

Here's the definition in eval.c:

struct BLOCK {
    NODE *var;
    NODE *body;
    VALUE self;
    struct FRAME frame;
    struct SCOPE *scope;
    struct BLOCKTAG *tag;
    VALUE klass;
    int iter;
    int vmode;
    int flags;
    struct RVarmap *dyna_vars;
    VALUE orig_thread;
    VALUE wrapper;
    struct BLOCK *prev;
};

....

static struct BLOCK *ruby_block;


I want to access the 'body' member of the struct and use it to get the AST 
for a proc.  It seems to me that if these structs were defined in an 
eval.h file, that would be easier ;-)
