In trying to get somewhere with [id://???] I wrote a quick XS library to gain access to some perl internal variables. My initial thought was to create an accessor for each variable I was interested in and just write a normal perl sub to format and print them. No such luck. My XSUB accessors returned globs instead of integers. I think this is really basic stuff but it still eluded me.

All I did was a basic `h2xs -n Devel::DebugScope`, edit the created .xs file to add my functions and run it. Eventually I just punted and did the dump right from the C code. I've included that bit as well.

 MODULE = Devel::DebugScope              PACKAGE = Devel::DebugScope  
+   PREFIX = ds_
 
 I32
 ds_scopestack_ix()
    CODE:
       RETVAL = PL_scopestack_ix;

 int
 ds_savestack_ix()
    CODE:
       RETVAL = PL_savestack_ix;
 
 void
 dump_scope()
    CODE:
       printf("scopestack_ix: %d\n", PL_scopestack_ix);
       printf("savestack_ix:  %d\n", PL_savestack_ix);
__END__
print savestack_ix() returns "*main::savestack_ix"

This is the part that eludes me. It should just be an integer and wher
+e the glob comes from... *shrug*
