[SOLVED] How does this tricky Perl code in Term::ShellUI using Term::ReadLine dereference an Array?

[rockyb]

I came across code like this in trying to work out a bug in Term::ReadLine::Perl5.

#!/usr/bin/perl
use strict;
use Term::ReadLine;
my $term = Term::ReadLine::Stub->new('test');
# $term is a blessed array reference
print $term, ' ', $term->OUT, "\n";
# output is: Term::ReadLine::Stub=ARRAY(0x9d73a7c) GLOB(0x9da48a8)

My question is how does $x->OUT seem to get to be the same thing as $x->[1] (if I have this right and I might not).

I find this confusing, do others as well? If so, given that for compatibility there the object is an array references, is there a less confusing way to write this. Or is this way preferable, given that's how it is in the documentation?

I should say that I think although Perl allows you to bless an array reference, I think it is a mistake in Term::Readline::Stub to do so.

Sorry for the noise, but it was mentioned in StackExchange that OUT is a method. So that mystery has been solved and I've deleted this on StackExchange.
