Okay, so what? Does it say, "There's no good reason to know how objects in Perl work."? My contention is simple, having this knowledge would likely result in some different choices being made depending on what is appropriate given the need.

This accessor could be implemented in two ways. I'm showing this as a read-only accessor because the read-write aspect isn't important for the example.

sub files {
  return $_[0]{'files'};
}

# OR

sub files {
  return @{ $_[0]{'files'} };
}

(And of course, there's the version that checks wantarray.)

OP's problem is that he assumed Moo did it the second way, when it actually does it the first way. I don't see how learning to write constructors and accessors from scratch would have helped figure out what the issue was.
