Hi ribasushi,

Thanks for the suggestion! I tried it out, and the module returns a bit more information than overload::Method(), but unless I missed something it unfortunately doesn't seem to directly answer the question whether an object will stringify via magic autogeneration or not, but I could probably figure it out based on all the information it returns. Here's an example of what the overload_info() function returns for two of my test classes from the original post: 

# this class stringifies even though "" is not directly overloaded
{
  "0+" => {
    class => "ICanStringify",
    code => sub { ... },
    code_name => "ICanStringify::__ANON__",
  },
  "fallback" => { class => "ICanStringify", value => undef },
}
# this class does not stringify
{
  "0+" => {
    class => "OnlyANumber",
    code => sub { ... },
    code_name => "OnlyANumber::__ANON__",
  },
  "fallback" => { class => "OnlyANumber", value => 0 },
}

Right now my current solution (posted below) of "just try it out" seems to work, so I'm a bit hesitant to change it except in a way that would simplify it. I'll look into it a bit more whether I can do so with the above info.

Thanks and Regards,
