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

-| Perl Host |
-+-----------+

-+-----------+ +-----------+
-| Perl Core |<->| Extension |
-+-----------+ +-----------+ ...
-
-Defining PERL_OBJECT has the following effects:
-
-PERL CORE
-1. CPerlObj is defined (this is the PERL_OBJECT)
-2. all static functions that needed to access either global
-variables or functions needed are made member functions
-3. all writable static variables are made member variables
-4. all global variables and functions are defined as:
- #define var CPerlObj::PL_var
- #define func CPerlObj::Perl_func
- * these are in embed.h
-This necessitated renaming some local variables and functions that
-had the same name as a global variable or function. This was
-probably a _good_ thing anyway.
-
-
-EXTENSIONS
-1. Access to global variables and perl functions is through a
-pointer to the PERL_OBJECT. This pointer type is CPerlObj*. This is
-made transparent to extension developers by the following macros:
- #define var pPerl->PL_var
- #define func pPerl->Perl_func
- * these are done in objXSUB.h
-This requires that the extension be compiled as C++, which means
-that the code must be ANSI C and not K&R C. For K&R extensions,
-please see the C API notes located in Win32/GenCAPI.pl. This script
-creates a perlCAPI.lib that provides a K & R compatible C interface
-to the PERL_OBJECT.
-2. Local variables and functions cannot have the same name as perl's
-variables or functions since the macros will redefine these. Look for
-this if you get some strange error message and it does not look like
-the code that you had written. This often happens with variables that
-are local to a function.
-
-PERL HOST
-1. The perl host is linked with perlX.lib to get perl_alloc. This
-function will return a pointer to CPerlObj (the PERL_OBJECT). It
-takes pointers to the various PerlXXX_YYY interfaces (see iperlsys.h
-for more information on this).
-2. The perl host calls the same functions as normally would be
-called in setting up and running a perl script, except that the
-functions are now member functions of the PERL_OBJECT.
