You are trying to treat something as a hash reference (i.e. doing this: ->{foobar}) but it's not a hash reference; it's some other kind of reference. (Given that the source of the data is YAML, I'd put my money on it being an array reference.)

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