/***********************************************************
* Changed all copyright messages to include 1993. * Stubs for faster implementation of local variables (not yet finished) * Added function name to code object. Print it for code and function objects. THIS MAKES THE .PYC FILE FORMAT INCOMPATIBLE (the version number has changed accordingly) * Print address of self for built-in methods * New internal functions getattro and setattro (getattr/setattr with string object arg) * Replaced "dictobject" with more powerful "mappingobject" * New per-type functio tp_hash to implement arbitrary object hashing, and hashobject() to interface to it * Added built-in functions hash(v) and hasattr(v, 'name') * classobject: made some functions static that accidentally weren't; added __hash__ special instance method to implement hash() * Added proper comparison for built-in methods and functions

/* Class object interface */
* Lots of small changes related to access. * Added "access *: ...", made access work for class methods. * Introduced subclass check: make sure that when calling ClassName.methodname(instance, ...), the instance is an instance of ClassName or of a subclass thereof (this might break some old code!)

Access checks now work, at least for instance data (not for methods yet). The class is now passed to eval_code and stored in the current frame. It is also stored in instance method objects. An "unbound" instance method is now returned when a function is retrieved through "classname.funcname", which when called passes the class to eval_code.

newclassobject gets a third parameter (optional class name)

extern object *newclassobject PROTO((object *, object *, object *));
Several changes in one: (1) dictionaries/mappings now have attributes values() and items() as well as keys(); at the C level, use the new function mappinggetnext() to iterate over a dictionary. (2) "class C(): ..." is now illegal; you must write "class C: ...". (3) Class objects now know their own name (finally!); and minor improvements to the way how classes, functions and methods are represented as strings. (4) Added an "access" statement and semantics. (This is still experimental -- as long as you don't use the keyword 'access' nothing should be changed.)

extern object *newinstanceobject PROTO((object *, object *));
Access checks now work, at least for instance data (not for methods yet). The class is now passed to eval_code and stored in the current frame. It is also stored in instance method objects. An "unbound" instance method is now returned when a function is retrieved through "classname.funcname", which when called passes the class to eval_code.

Changes so that user-defined classes can implement operations invoked by special syntax: you can now define your own numbers, sequences and mappings.
