NAME

Perl::Critic::Policy::ValuesAndExpressions::ProhibitInterpolationOfLiterals

DESCRIPTION

Don't use double-quotes or qq// if your string doesn't require interpolation. This saves the interpreter a bit of work and it lets the reader know that you really did intend the string to be literal.

print "foobar";     #not ok
print 'foobar';     #ok
print qq/foobar/;   #not ok
print q/foobar/;    #ok

print "$foobar";    #ok
print "foobar\n";   #ok
print qq/$foobar/;  #ok
print qq/foobar\n/; #ok
