       Perl::Critic::Policy::ValuesAndExpressions::ProhibitQuotesAsQuotelikeOperatorDelimiters -
       Don't use quotes ("'", """, "`") as delimiters for the quote-like operators.


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


       With the obvious exception of using single-quotes to prevent interpolation, using quotes
       with the quote-like operators kind of defeats the purpose of them and produces obfuscated
       code, causing problems for future maintainers and their editors/IDEs.

           $x = q"q";                #not ok
           $x = q'q';                #not ok
           $x = q`q`;                #not ok

           $x = qq"q";               #not ok
           $x = qr"r";               #not ok
           $x = qw"w";               #not ok

           $x = qx`date`;            #not ok

           $x =~ m"m";               #not ok
           $x =~ s"s"x";             #not ok
           $x =~ tr"t"r";            #not ok
           $x =~ y"x"y";             #not ok

           $x =~ m'$x';              #ok
           $x =~ s'$x'y';            #ok
           $x = qr'$x'm;             #ok
           $x = qx'finger foo@bar';  #ok


       This policy has three options: "single_quote_allowed_operators",
       "double_quote_allowed_operators", and "back_quote_allowed_operators", which control which
       operators are allowed to use each of "'", """, "`" as delimiters, respectively.

       The values allowed for these options are a whitespace delimited selection of the "m", "q",
       "qq", "qr", "qw", "qx", "s", "tr", and "y" operators.

       By default, double quotes and back quotes (backticks) are not allowed as delimiters for
       any operators and single quotes are allowed as delimiters for the "m", "qr", "qx", and "s"
       operators.  These defaults are equivalent to having the following in your .perlcriticrc:

           single_quote_allowed_operators = m s qr qx
           double_quote_allowed_operators =
           back_quote_allowed_operators =
