inspect and inspect_str from PIR

[Jonathan Worthington]

Hi,

I've now got the inspect_str and inspect vtable methods implemented for 
the Class PMC, and the method "attributes", "methods", "roles" and 
"parents" delegate to inspect_str (and that's testable and working).

However, there is no way (unless I'm missing it) in PDD15 to call 
inspect and inspect_str directly from PIR. Should be have inspect_p and 
inspect_p_s ops? Should we also have a method on the Class (one of those 
later to move out to a role) like "inspect(STRING *what :optional)"? I'd 
like to have both the ops for interoperability and the method for nice 
interfaceness.

Thanks,

Jonathan
