>perl -wMstrict -MData::Dump -le "use Readonly; ;; Readonly my %h => (a => {b => {c => {d => 1}}}); dd \%h; ;; $h{a}{b}{d} = 2; " { # tied Readonly::Hash a => { # tied Readonly::Hash b => { # tied Readonly::Hash c => { # tied Readonly::Hash d => 1, }, }, }, } Modification of a read-only value attempted at -e line 1
