Nearly any encoding problem makes me go bonkers.

Recently, I had a function that took a WWW::Curl object and some parameters, which then sets the parameters on the Curl object. Something like this:

set_opts({
    curl => $curl,
    url  => 'http://www.example.com/path/',
    . . . 
});

When $curl->perform method was called to run the query, no query was actually being sent. After doing some debugging, I found out that the URL within the object was gibberish.

I fixed it by changing the set_opts() parameter like this:

set_opts( 'http://www.example.com/path/', {
    curl => $curl,
    . . . 
});

Which shouldn't have any effect in a sane world, but in a world where encoding issues come up, it does.

I swear that encoding problems are non-deterministic, and should be used as a cryptographically-secure source of random numbers.
