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 allocated space in the padlist.  Note that the last
pad may be in an earlier slot.  Any entries following it will be C<NULL> in
that case.

The names associated with pad entries.

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.

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 C<NULL> for a target
slot.
=for apidoc Amx|STRLEN|PadnameLEN|PADNAME * pn
The length of the name.
=for apidoc Amx|bool|PadnameUTF8|PADNAME * pn
Whether PadnamePV is in UTF-8.  Currently, this is always true.

Returns the pad name as a mortal SV.
=for apidoc m|bool|PadnameIsOUR|PADNAME * pn
Whether this is an "our" variable.

The stash in which this "our" variable was declared.
=for apidoc m|bool|PadnameOUTER|PADNAME * pn
Whether this entry belongs to an outer pad.  Entries for which this is true
are often referred to as 'fake'.
=for apidoc m|bool|PadnameIsSTATE|PADNAME * pn
Whether this is a "state" variable.
=for apidoc m|bool|PadnameIsFIELD|PADNAME * pn
Whether this is a "field" variable.  PADNAMEs where this is true will
have additional information available via C<PadnameFIELDINFO>.
=for apidoc m|HV *|PadnameTYPE|PADNAME * pn

for C<my Foo $bar>.

=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

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 C<opad>, then make the
current pad equal to C<npad>
