+Returns the glob with the given C<name> and a defined subroutine or
+C<NULL>. The glob lives in the given C<stash>, or in the stashes
+accessible via @ISA and @UNIVERSAL.
+
+The argument C<level> should be either 0 or -1. If C<level==0>, as a
+side-effect creates a glob with the given C<name> in the given C<stash>
+which in the case of success contains an alias for the subroutine, and sets
+up caching info for this glob. Similarly for all the searched stashes.
+
+This function grants C<"SUPER"> token as a postfix of the stash name. The
+GV returned from C<gv_fetchmeth> may be a method cache entry, which is not
+visible to Perl code. So when calling C<perl_call_sv>, you should not use
+the GV directly; instead, you should use the method's CV, which can be
+obtained from the GV with the C<GvCV> macro.

+Returns the glob which contains the subroutine to call to invoke the method
+on the C<stash>. In fact in the presence of autoloading this may be the
+glob for "AUTOLOAD". In this case the corresponding variable $AUTOLOAD is
+already setup.
+
+The third parameter of C<gv_fetchmethod_autoload> determines whether
+AUTOLOAD lookup is performed if the given method is not present: non-zero
+means yes, look for AUTOLOAD; zero means no, don't look for AUTOLOAD.
+Calling C<gv_fetchmethod> is equivalent to calling C<gv_fetchmethod_autoload>
+with a non-zero C<autoload> parameter.
+
+These functions grant C<"SUPER"> token as a prefix of the method name. Note
+that if you want to keep the returned glob for a long time, you need to
+check for it being "AUTOLOAD", since at the later time the call may load a
+different subroutine due to $AUTOLOAD changing its value. Use the glob
+created via a side effect to do this.
+
+These functions have the same side-effects and as C<gv_fetchmeth> with
+C<level==0>. C<name> should be writable if contains C<':'> or C<'
+''>. The warning against passing the GV returned by C<gv_fetchmeth> to
+C<perl_call_sv> apply equally to these functions.
