Hi,

looking at the code of Memoize::Expire on line 56 of the current version 

$self->{C}{$key} = $header . $value;

[download]
let me assume that there is a bug or it was never intended to use this module in list context. In your case $value is an array ref, which gets stringified by this operation. When fetching this value you get the error you presented.

I'm sorry, but in this case I can only cite the man page to this module

This module is experimental, and may contain bugs. Please report bugs to the address below.

Best regards
McA
