Won't that create the my variables inside the scope of your sub, which will then go out of scope pretty much immediately? I don't think the OP is asking the right question because s/he's talking about package-scope variables, which are, by their nature, global, not lexical. In that case, it becomes much easier: 

for (@attributes)
{
  no strict 'refs';
  ${$package . '::' . $_} = do {
    ... something to do with $_ ...
  };
}

Of course, if $package is supposed to be this package, then that is a bit simpler - change $package to __PACKAGE__, and you're done.

Update: now that diotalevi has added some extra ellipses, I can see how he's proposing to do this without the variables going out of scope. And now I think I better understand the OP's question, which has nothing to do with globals because he's trying to create a variable that is a string. And that string just happens to look like a global variable name.

In this case, I'd suggest a number of possibilities. First thing to come to my head is stupid, so I'm going to skip that one. ;-) The next idea is to just create the constants that you're going to need using constant:

  use constant {
    map {
      uc $_ => __PACKAGE__ . "::$_"
    } qw(name timestamp etc.)
  };

Then you don't need to keep redeclaring anything.

(I said a number of possibilities, right?) Still, use a hash. The usage would be something like $self->{$my{name}} which is still a lot lighter than $self->{__PACKAGE . '::name'}

And back to the stupid one. Create a package, say called "My" or "P" or something. Set up an AUTOLOAD function which looks at the package of the caller, and just returns that package name concatenated with '::' and then the function being called. Usage would then be $self->{P->name}

But don't do that last one.
