sv_magic()----------av.cav_store()	Storing a non-undef element into an SMAGICAL array, av,	assigns the equivalent lowercase form of magic (of the first	MAGIC in the chain) to the value (with obj = av, name = 0 and	namlen = array index).gv.cgv_init()	Initialising gv assigns '*' magic to it with obj = gv, name =	GvNAME and namlen = GvNAMELEN.gv_fetchpv()	@ISA gets 'I' magic with obj = gv, zero name and namlen.	%OVERLOAD gets 'A' magic with obj = gv, zero name and namlen.	$1 to $9, $&, $`, $', $+ get '\0' magic with obj = gv,	name = GvNAME and namlen = len ( = 1 presumably).Gv_AMupdate()	Stashes for overload magic seem to get 'c' magic with obj = 0,	name = &amt and namlen = sizeof(amt).hv_magic(hv, gv, how)	Gives magic how to hv with obj = gv and zero name and namlen.mg.cmg_copy(sv, nsv, key, klen)	Traverses the magic chain of sv. Upper case forms of magic	(only) are copied across to nsv, preserving obj but using	name = key and namlen = klen.magic_setpos()	LvTARG of a PVLV gets 'g' magic with obj = name = 0 and namlen = pos.op.cmod()	PVLV operators give magic to their targs with	obj = name = namlen = 0. OP_POS gives '.', OP_VEC gives 'v'	and OP_SUBSTR gives 'x'.perl.cmagicname(sym, name, namlen)	Fetches/creates a GV with name sym and gives it '\0' magic	with obj = gv, name and namlen as passed.init_postdump_symbols()	Elements of the environment get given SVs with 'e' magic.	obj = sv and name and namlen point to the actual string	within env.pp.cpp_av2arylen()	$#foo gives '#' magic to the new SV with obj = av and	name = namlen = 0.pp_study()	SV gets 'g' magic with obj = name = namlen = 0.pp_substr()	PVLV gets 'x' magic with obj = name = namlen = 0.pp_vec()	PVLV gets 'x' magic with obj = name = namlen = 0.pp_hot.cpp_match()	m//g gets 'g' magic with obj = name = namlen = 0.pp_sys.cpp_tie()	sv gets magic with obj = sv and name = namlen = 0.	If an HV or an AV, it gets 'P' magic, otherwise 'q' magic.pp_dbmopen()	'P' magic for the HV just as with pp_tie().pp_sysread()	If tainting, the buffer SV gets 't' magic with	obj = name = namlen = 0.sv.csv_setsv()	Doing sv_setsv(dstr, gv) gives '*' magic to dstr with	obj = dstr, name = GvNAME, namlen = GvNAMELEN.util.cfbm_compile()	The PVBM gets 'B' magic with obj = name = namlen = 0 and SvVALID	is set to indicate that the Boyer-Moore table is valid.	magic_setbm() just clears the SvVALID flag.hv_magic()----------gv.cgv_fetchfile()	With perldb, the HV of a gvfile gv gets 'L' magic with obj = gv.gv_fetchpv()	%SIG gets 'S' magic with obj = siggv.init_postdump_symbols()	%ENV gets 'E' magic with obj = envgv.
