in thread Dualvars besides $!

The latest Scalar::Util::isdual considers FLAGS = (GMG,SMG,pNOK,pPOK) to be a dualvar. (No idea about earlier versions, but I suspect it's the same.) The docs are wrong. The following returns 1 for both 5.8.9 and 5.18.1, while the docs say it returns false:

perl -MScalar::Util=isdual -MDevel::Peek \ -e'$!=1; print("$!\n"); print(isdual($!)?1:0,"\n"); Dump($!);'

Nit: $! is magical (like tied variables), but it's not a tied variable like the docs say.
