What is wrong with nested while loops?

Nothing. They are great. I have no idea what you are doing with them in your example. As far as I can see, they are pointless.

What is wrong with using next statements within the while loops?

Nothing, that's what they are for. I have no idea what you are doing with them in your example. As far as I can see, they are pointless.

What is wrong with instructing the resumption of the outermost while loop?

Well, you are telling it to resume what it is already doing? It's wrong in the sense that it's entirely pointless. You don't have to tell a loop to loop. Just let it loop.

There isn't anything wrong with any of the basic concepts here, rather the problem is that you've pasted them randomly into lump of code that is surely without function or meaning. Your description of this code as a dream is entirely appropriate.

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.
