	80	/* PERL_OBJECT explained - DickH and DougL @ ActiveState.com
	81
	82	Defining PERL_OBJECT turns on creation of a C++ object that
	83	contains all writable core perl global variables and functions.
	84	Stated another way, all necessary global variables and functions
	85	are members of a big C++ object. This object's class is CPerlObj.
	86	This allows a Perl Host to have multiple, independent perl
	87	interpreters in the same process space. This is very important on
	88	Win32 systems as the overhead of process creation is quite high --
	89	this could be even higher than the script compile and execute time
	90	for small scripts.
	91
	92	The perl executable implementation on Win32 is composed of perl.exe
	93	(the Perl Host) and perlX.dll. (the Perl Core). This allows the
	94	same Perl Core to easily be embedded in other applications that use
	95	the perl interpreter.

	105	+-----------+ +-----------+ ...
	106
	107	Defining PERL_OBJECT has the following effects:
	108
	109	PERL CORE
	110	1. CPerlObj is defined (this is the PERL_OBJECT)
	111	2. all static functions that needed to access either global
	112	variables or functions needed are made member functions
	113	3. all writable static variables are made member variables
	114	4. all global variables and functions are defined as:
	115	#define var CPerlObj::PL_var
	116	#define func CPerlObj::Perl_func
	117	* these are in embed.h
	118	This necessitated renaming some local variables and functions that
	119	had the same name as a global variable or function. This was
	120	probably a _good_ thing anyway.
	121
	122
	123	EXTENSIONS
	124	1. Access to global variables and perl functions is through a
	125	pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
	126	made transparent to extension developers by the following macros:
	127	#define var pPerl->PL_var
	128	#define func pPerl->Perl_func
	129	* these are done in objXSUB.h
	130	This requires that the extension be compiled as C++, which means
	131	that the code must be ANSI C and not K&R C. For K&R extensions,
	132	please see the C API notes located in Win32/GenCAPI.pl. This script
	133	creates a perlCAPI.lib that provides a K & R compatible C interface
	134	to the PERL_OBJECT.
	135	2. Local variables and functions cannot have the same name as perl's
	136	variables or functions since the macros will redefine these. Look for
	137	this if you get some strange error message and it does not look like
	138	the code that you had written. This often happens with variables that
	139	are local to a function.
	140
	141	PERL HOST
	142	1. The perl host is linked with perlX.lib to get perl_alloc. This
	143	function will return a pointer to CPerlObj (the PERL_OBJECT). It
	144	takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
	145	for more information on this).
	146	2. The perl host calls the same functions as normally would be
	147	called in setting up and running a perl script, except that the
	148	functions are now member functions of the PERL_OBJECT.
