1. yes

2. no and yes (perl treats while1 as one identifier)

3a. yes

8a. yes, cool, unexpected solution :-)   our official version uses a much much more obscure trick.. funny we never saw this one
Try this instead: eval(q[$$foo]) ne eval(q["$$foo"])
•Update: actually, no, the original was fine too.. even though $$foo and $$foo + 0 print differently, they don't compare numerically unequal, which is what the exercise was

11. doesn't appear to work for me..

% perl -e 'sub STDOUT{\*STDOUT} <STDOUT> eq <+STDOUT> or die' Died at -e line 1.

12. yes, but why? :-)

•Update: fixed the "try this".. initially said "!=" instead of "ne"

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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.
