Perl, "closure" using Hash
- by Mike
I would like to have a subroutine as a member of a hash which is able to have access to other hash members.
For example
sub setup {
%a = (
txt => "hello world",
print_hello => sub {
print ${txt};
})
return %a
}
my %obj = setup();
$obj{print_hello};
Ideally this would output "hello world"
