You could use AUTOLOAD to avoid hacking the symbol table.
Update:
One of our fellow monks asked for an example.
So here is very simplified one.
#!/usr/bin/perl
use v5.12;
use warnings FATAL => 'all';
package Attr;
use Carp;
my %attr = (one => 1, two => 2);
sub new {
my $class = shift;
bless {}, $class;
}
our $AUTOLOAD;
# Generic setter/getter
sub AUTOLOAD {
my $self = shift;
my $called = $AUTOLOAD =~ s/.*:://r;
croak "$AUTOLOAD: no such method" unless exists $attr{$called};
if (@_ > 0) {
$self->{$called} = shift;
} else {
return $self->{$called};
}
}
package main;
my $attr = Attr->new;
$attr->one('uno');
say $attr->one;
eval {say $attr->three};
say $@ if $@;
__DATA__
uno
Attr::three: no such method at /home/jo/Programs/play-scripts/pm-11125
