Taint gets added at the sv_catpvn of "::" here in Perl_yylex():
else {
sv_setsv(PL_subname,PL_curstname);
sv_catpvn(PL_subname,"::",2);
sv_catpvn(PL_subname,tmpbuf,len);
}
So I'm starting to wonder if the code in Perl_leave_scope() that sets
PL_localizing = 2 is a hack to remove tainting that probably never should have
been there.
