I think you're wrong about clearer.

But bedsides that, it does not do (and cannot me made to do), the same thing:

@a = map{ m[(..)(.)]g } 'the quick brown fox', 'jumps over the lazy do +g';; print @a;; th e q u ic k b r ow n f o ju m ps ov e r t he la z y d @a = map{ m[(..)(.)]g; $1 || () } 'the quick brown fox', 'jumps over t +he lazy dog';; print @a;; th ju

Perl is context sensitive. If you do not understand what that is, or try ignore it, you will never make best use of Perl.

On the other hand, if you take a few hours or days to understand context sensitivity, the OPs code is clear, concise, and very readable.

And very powerful. It requires many extra, contorted (and ultimately redundant) lines of code to achieve the same thing without using the effects of list context. It is a tool, that once you've realised its powerful simplicity, you will not want to do without.

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.
