It seems that all your 6 points here are good programming practice as a matter of course.

  1. Typeglobs (maybe)
    There are some circumstances when messing with stashes, for example, when typeglobs are unavoidable. However, These bits of code can probably be written much cleaner in Perl6.

  2. Odd syntactic corner cases (Like some of the JAPHish things)
    Avoid unless obfu-ing or golfing. These are certainly defeating the aim of code clarity.

  3. Version specific behavior (hash ordering)
    is asking for trouble anyway.

  4. Numeric size assumptions (32-bit ints, # of bits in a float mantissa)
    defeats the aim of portability.

  5. Low-level interfaces (like the raw source filter interface, not what Filter::Simple provides)
    OK, but why re-invent the wheel anyway?

  6. Ordering of operations at undefined points (like when $foo = $i++ + $i++ increments $i)
    yyeughh! Need I say more.

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


    1. Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
    2. Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
    3. Read Where should I post X? if you're not absolutely sure you're posting in the right place.
    4. Please read these before you post! —
    5. Posts may use any of the Perl Monks Approved HTML tags:
      a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
    6. You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
              For:     Use:
      & &amp;
      < &lt;
      > &gt;
      [ &#91;
      ] &#93;
    7. Link using PerlMonks shortcuts! What shortcuts can I use for linking?
