If you had a time machine, which Perl language mis-feature would you expunge from existence?

• Barewords (no Sharon poetry mode :)
• Bareword file handles.
• Two-argument open
• Indirect object notation (see effective perler)
• Formats (see effective perler)
• Old-style subroutine prototypes (see effective perler)
• Postfix if
• unless
• until
• do blocks
• String eval (see Re^3: Create sort function from a text file (string eval vs block eval))
• Change spelling of block eval to try (see last para of Re^3: Create sort function from a text file (string eval vs block eval))
• Lvalue substr
• <...> (i.e. just use the glob function)
• select filehandles (e.g. select((select($fh), $|=1)[0]) vs $fh->autoflush() - see On Interfaces and APIs)
• Calling subroutines with a leading &
• Symbolic references
• Pseudohashes
• C-style for statements
• Make use strict and use warnings the default

There are surely others I've not thought of. Suggestions welcome.

This poll was provoked by two spookily similar replies I happened to make today: Re^2: Organizational Culture (Part VI): Sociology and Re^3: Create sort function from a text file (string eval vs block eval).

Update (much later):

• The impossibility of performing a sound static parse of Perl (BTW this has been fixed in Raku)

  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.
