B<they are not for use in extensions>!

=item is_gv_magical

Returns C<TRUE> if given the name of a magical GV.

Currently only useful internally when determining if a GV should be

created even in rvalue contexts.

C<flags> is not used at present but available for future extension to

allow selecting particular classes of magical variable.

bool is_gv_magical(char *name, STRLEN len, U32 flags)

=item LVRET

True if this op will be the return value of an lvalue subroutine

=item PL_DBsingle

When Perl is run in debugging mode, with the B<-d> switch, this SV is a

boolean which indicates whether subs are being single-stepped.

Single-stepping is automatically turned on after every step. This is the C

variable which corresponds to Perl's $DB::single variable. See

C<PL_DBsub>.
