Perl::Critic::Policy::ValuesAndExpressions::ProhibitNoisyQuotes3pm

Use "q{}" or "qq{}" instead of quotes for awkward-looking strings.

Affiliation

This Policy is part of the core Perl::Critic distribution.

Overview

Don't use quotes for one or two-character strings of non-alphanumeric characters (i.e. noise). These tend to be hard to read. For legibility, use "q{}" or a named value. However, braces, parentheses and brackets tend to look better in quotes, so those are allowed.

    $str = join ',', @list;     #not ok
    $str = join ",", @list;     #not ok
    $str = join q{,}, @list;    #better
    $COMMA = q{,};
    $str = join $COMMA, @list;  #best
    $lbrace = '(';          #ok
    $rbrace = ')';          #ok
    print '(', @list, ')';  #ok

Configuration

This Policy is not configurable except for the standard options.
