( [id://3333]=superdoc: print w/replies, xml ) Need Help??

I voted for the first option because I think it is mnemonic, but some of the others are also

  • ~>: (hand)wavy deref.
  • ?> & ?->: questionable deref. (With a preference for the shorter.)

With ->? it looks like the test comes after the deref.

+> & !> just look like typos.

->-> looks like a double deref, rather than a single conditional one.

I find all those using & anti-mnemonic in that elsewhere it takes a reference, rather than dereferences one.

And those containing = look much too much like a fat comma. The parser may be able to distinguish them, but I don't think my brain would.


With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?

Title:
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.
