+=head1 GV Handling
A GV is a structure which corresponds to to a Perl typeglob, ie *foo.
It is a structure that holds a pointer to a scalar, an array, a hash etc,
corresponding to $foo, @foo, %foo.
GVs are usually found as values in stashes (symbol table hashes) where
Perl stores its global variables.

+
+These all return the GV of type C<sv_type> whose name is given by the inputs,
+or NULL if no GV of that name and type could be found. See L<perlguts/Stashes
+and Globs>.
+
+The only differences are how the input name is specified, and if 'get' magic is
+normally used in getting that name.
+
+Don't be fooled by the fact that only one form has C<flags> in its name. They
+all have a C<flags> parameter in fact, and all the flag bits have the same
+meanings for all
+
+If any of the flags C<GV_ADD>, C<GV_ADDMG>, C<GV_ADDWARN>, C<GV_ADDMULTI>, or
+C<GV_NOINIT> is set, a GV is created if none already exists for the input name
+and type. However, C<GV_ADDMG> will only do the creation for magical GV's.
+For all of these flags except C<GV_NOINIT>, C<L</gv_init_pvn>> is called after
+the addition. C<GV_ADDWARN> is used when the caller expects that adding won't
+be necessary because the symbol should already exist; but if not, add it
+anyway, with a warning that it was unexpectedly absent. The C<GV_ADDMULTI>
+flag means to pretend that the GV has been seen before (I<i.e.>, suppress "Used
+once" warnings).
+
+The flag C<GV_NOADD_NOINIT> causes C<L</gv_init_pvn>> not be to called if the
+GV existed but isn't PVGV.
+
+If the C<SVf_UTF8> bit is set, the name is treated as being encoded in UTF-8;
+otherwise the name won't be considered to be UTF-8 in the C<pv>-named forms,
+and the UTF-8ness of the underlying SVs will be used in the C<sv> forms.
+
+If the flag C<GV_NOTQUAL> is set, the caller warrants that the input name is a
+plain symbol name, not qualified with a package, otherwise the name is checked
+for being a qualified one.
+
+In C<gv_fetchpv>, C<nambeg> is a C string, NUL-terminated with no intermediate
+NULs.
+
+In C<gv_fetchpvs>, C<name> is a literal C string, hence is enclosed in
+double quotes.
+
+C<gv_fetchpvn> and C<gv_fetchpvn_flags> are identical. In these, <nambeg> is
+a Perl string whose byte length is given by C<full_len>, and may contain
+embedded NULs.
+
+In C<gv_fetchsv> and C<gv_fetchsv_nomg>, the name is extracted from the PV of
+the input C<name> SV. The only difference between these two forms is that
+'get' magic is normally done on C<name> in C<gv_fetchsv>, and always skipped
+with C<gv_fetchsv_nomg>. Including C<GV_NO_SVGMAGIC> in the C<flags> parameter
+to C<gv_fetchsv> makes it behave identically to C<gv_fetchsv_nomg>.
