The SVs in the names AV have their PV being the name of the variable.
NV+1..IV inclusive is a range of cop_seq numbers for which the name is
valid. For typed lexicals name SV is SVt_PVMG and SvSTASH points at the
-type. For C<our> lexicals, the type is also SVt_PVGV, with the MAGIC slot
+type. For C<our> lexicals, the type is also SVt_PVMG, with the OURSTASH slot
pointing at the stash of the associated global (so that duplicate C<our>
declarations in the same package can be detected). SvCUR is sometimes
hijacked to store the generation number during compilation.
