in thread Use of "my" after Perl v5.14

I think $TRUE variable will not be visible in second file from t2 package.. Because it is declared to be private in that package.. Will it show compiler error??

    I didn't get an error. But then I am not using v5.14.

      You're also not using warnings, which would have made Perl complain about "Use of uninitialized value $t2::TRUE in concatenation (.) or string at t3.pl line 7" (line 7 in my altered file) regardless of Perl version. Note also that
          print " my:  \$t2::TRUE        = '$t2::TRUE'\n";
      prints
          my:  $t2::TRUE        = ''
      (empty single-quotes instead of '1') with or without warnings.

      Update: Upon re-reading your post, it occurs to me that your intention may have been to point up the fact that the value of the lexical  $TRUE defined in the  .pm file is not visible in the  .pl file ("Pay attention to the value of $TRUE in the sample..."). If so, I offer my own apologies! (In any event, the use of warnings remains a valuable, albeit implicit, recommendation.)
