I'm just saying that for good code structure, especially in printf situaitons where a template bit matches a data argument, doing one at a time give you a virtual array of lines where the template is right by the data and any comment, one field a line, give or take the occasional adjacent series of constants.

At a higher level, put all or minority record types in separate subroutines, so the flow is simple to follow: writeHeader, while ... writeData, writeTrailer.

perl::critic::policy::valuesandexpressions::requireinterpolation

Perl::Critic::Policy::ValuesAndExpressions::RequireInterUsertContribPerl::Critic::Policy::ValuesAndExpressions::RequireInterpolationOfMetachars(3)

NAME

       Perl::Critic::Policy::ValuesAndExpressions::RequireInterpolationOfMetachars - Warns that you might have used single quotes when you really
       wanted double-quotes.

AFFILIATION

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

DESCRIPTION

       This policy warns you if you use single-quotes or "q//" with a string that has unescaped metacharacters that may need interpolation. Its
       hard to know for sure if a string really should be interpolated without looking into the symbol table.  This policy just makes an educated
       guess by looking for metacharacters and sigils which usually indicate that the string should be interpolated.

   Exceptions
       o   Variable names to "use vars":

	       use vars '$x';	       # ok
	       use vars ('$y', '$z');  # ok
	       use vars qw< $a $b >;   # ok

       o   Things that look like e-mail addresses:

	       print 'john@foo.com';	       # ok
	       $address = 'suzy.bar@baz.net';  # ok

CONFIGURATION

       The "rcs_keywords" option allows you to stop this policy from complaining about things that look like RCS variables, for example, in
       deriving values for $VERSION variables.

       For example, if you've got code like

	   our ($VERSION) = (q<$Revision: 4126 $> =~ m/(d+)/mx);

       You can specify

	   [ValuesAndExpressions::RequireInterpolationOfMetachars]
	   rcs_keywords = Revision

       in your .perlcriticrc to provide an exemption.

NOTES

       Perl's own "warnings" pragma also warns you about this.
