/* Note: the following three macros are actually defined in scope.h, but
 * they are documented here for completeness, since they directly or
 * indirectly affect pads.

=for apidoc m|void|SAVEPADSV	|PADOFFSET po
Save a pad slot (used to restore after an iteration)

XXX DAPM it would make more sense to make the arg a PADOFFSET
=for apidoc m|void|SAVECLEARSV	|SV **svp
Clear the pointed to pad value on scope exit. (i.e. the runtime action of 'my')

=for apidoc m|void|SAVECOMPPAD
save PL_comppad and PL_curpad


=for apidoc Amx|PAD **|PadlistARRAY|PADLIST padlist
The C array of a padlist, containing the pads.  Only subscript it with
numbers >= 1, as the 0th entry is not guaranteed to remain usable.

=for apidoc Amx|SSize_t|PadlistMAX|PADLIST padlist
The index of the last pad in the padlist.

=for apidoc Amx|PADNAMELIST *|PadlistNAMES|PADLIST padlist
The names associated with pad entries.

=for apidoc Amx|PADNAME **|PadlistNAMESARRAY|PADLIST padlist
The C array of pad names.

=for apidoc Amx|SSize_t|PadlistNAMESMAX|PADLIST padlist
The index of the last pad name.

=for apidoc Amx|U32|PadlistREFCNT|PADLIST padlist
The reference count of the padlist.  Currently this is always 1.

=for apidoc Amx|PADNAME **|PadnamelistARRAY|PADNAMELIST pnl
The C array of pad names.

=for apidoc Amx|SSize_t|PadnamelistMAX|PADNAMELIST pnl
The index of the last pad name.

=for apidoc Amx|SV **|PadARRAY|PAD pad
The C array of pad entries.

=for apidoc Amx|SSize_t|PadMAX|PAD pad
The index of the last pad entry.

=for apidoc Amx|char *|PadnamePV|PADNAME pn	
The name stored in the pad name struct.  This returns NULL for a target or
GV slot.

=for apidoc Amx|STRLEN|PadnameLEN|PADNAME pn	
The length of the name.

=for apidoc Amx|bool|PadnameUTF8|PADNAME pn
Whether PadnamePV is in UTF8.

=for apidoc Amx|SV *|PadnameSV|PADNAME pn
Returns the pad name as an SV.  This is currently just C<pn>.  It will
begin returning a new mortal SV if pad names ever stop being SVs.

=for apidoc m|bool|PadnameIsOUR|PADNAME pn
Whether this is an "our" variable.

=for apidoc m|HV *|PadnameOURSTASH
The stash in which this "our" variable was declared.

=for apidoc m|bool|PadnameOUTER|PADNAME pn
Whether this entry belongs to an outer pad.

=for apidoc m|bool|PadnameIsSTATE|PADNAME pn
Whether this is a "state" variable.

=for apidoc m|HV *|PadnameTYPE|PADNAME pn
The stash associated with a typed lexical.  This returns the %Foo:: hash
for C<my Foo $bar>.


=for apidoc m|SV *|PAD_SETSV	|PADOFFSET po|SV* sv
Set the slot at offset C<po> in the current pad to C<sv>

=for apidoc m|void|PAD_SV	|PADOFFSET po
Get the value at offset C<po> in the current pad

=for apidoc m|SV *|PAD_SVl	|PADOFFSET po
Lightweight and lvalue version of C<PAD_SV>.
Get or set the value at offset C<po> in the current pad.
Unlike C<PAD_SV>, does not print diagnostics with -DX.
For internal use only.

=for apidoc m|SV *|PAD_BASE_SV	|PADLIST padlist|PADOFFSET po
Get the value from slot C<po> in the base (DEPTH=1) pad of a padlist

=for apidoc m|void|PAD_SET_CUR	|PADLIST padlist|I32 n
Set the current pad to be pad C<n> in the padlist, saving
the previous current pad. NB currently this macro expands to a string too
long for some compilers, so it's best to replace it with

    SAVECOMPPAD();
    PAD_SET_CUR_NOSAVE(padlist,n);


=for apidoc m|void|PAD_SET_CUR_NOSAVE	|PADLIST padlist|I32 n
like PAD_SET_CUR, but without the save

=for apidoc m|void|PAD_SAVE_SETNULLPAD
Save the current pad then set it to null.

=for apidoc m|void|PAD_SAVE_LOCAL|PAD *opad|PAD *npad
Save the current pad to the local variable opad, then make the
current pad equal to npad

=for apidoc m|void|PAD_RESTORE_LOCAL|PAD *opad
Restore the old pad saved into the local variable opad by PAD_SAVE_LOCAL()
