"Minor issue: finding the classname (e.g. ref($ret)) is part of deciding if sub returned an error, for example when sub normally returns a blessed object instead of unblessed ref (as in my example)."

Sorry, but I don't understand this. My code using blessed clearly distinguished "Error" from "Success". Your line:

die "@$ret" if ref($ret) eq 'YouveGotError';
[download]

could be rewritten as:

die "@$ret" if $err eq 'YouveGotError';
[download]

If I change 'blessed $ret' in my code, to 'ref $ret', the output becomes:

Run: 1
Error "ARRAY" detected
Code: 42
Errstr: 43
Run: 2
Error "YouveGotError" detected
Code: 0
Errstr: error was ...
[download]

which, I'm pretty sure, is not what you want.

I suspect we may be talking at cross-purposes, or there's some other misunderstanding; however, I've looked back over our posts, and can't see what the problem might be.

"apropos the edits: ..."

No need to apologise. I just wanted to make it clear what I was responding to. There was no intended rebuke or other negativity.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
