in thread How do you find keys of a Blessed Hash?

keys $blessed doesn't work for a very good reason. keys can (in recent versions of Perl) be used with either arrays or hashes. A blessed object can (thanks to overload) be simultaneously dereferencable as a hash and and array. So for blessed objects, you need to manually dereference.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
