Changing the properties of the attributes works in the role:
#!/usr/bin/perl use warnings; use strict; { package MyRole; use Moo::Role; has +x => (is => 'ro'); } { package MyObj; use Moo; has x => (is => 'rw'); sub finalize { 'Moo::Role'->apply_roles_to_object($_[0], 'MyRole'); } } my $o = 'MyObj'->new; $o->x(12); $o->finalize; $o->x(13); # x is a read-only accessor

Another way is to wrap the accessor:

{ package MyRole; use Moo::Role; requires 'x'; before x => sub { die "x is read only" if @_ > 1 }; }

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord }map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,
