Sommaire

NAME

Perl::Critic::Policy::ValuesAndExpressions::ProhibitNoisyQuotes - Use "q{}" or "qq{}" instead of quotes for awkward-looking strings.

AFFILIATION

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

DESCRIPTION

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 do 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.
