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

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