I'll answer only to 1st item, because I see 2nd already resolved.

As best of my understanding, yes, ref count for $depth is increased when "sub recurse" is compiled. And if, say, we compiled anonymous sub as my $r=sub{$depth} and then $r goes away due to refcounting, I see that ref count for $depth will be decreased once (even if $depth was used several times inside that sub).

Let me note that I just checked "perlsub" and see exactly your question explained at the section "Persistent Private Variables"

PS. Something fishy is going on there, or my name is Vadim Konovalov. And it's not.

Are you posting in the right place? Check out Where do I post X? to know for sure.
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.
