in reply to Behaving appropriately based on ref() result

Data::Rmap has code doing something like this and may meet your needs. It just uses Scalar::Utils::reftype and if/elses.

ref() can return anything for blessed objects 

perl -le 'print ref(bless{},"Hello World")'

Scalar util's reftype is better for this job.

    Except that it (Scalar::Util::reftype()) can't tell a regexp from a ref to a scalar.
