Not exactly : to use a new pragma, you have to modify your code, and implicitly state you require perl >= 5.X. Your old code will run unmodified. But, if we change the meaning of use strict, and if that forces you to modify your code to cope with a new strict subpragma, you make it dependent on perl >= 5.X without really needing to. (I was assuming that C<use strict> continues to enable all strict subpragmas)Thread Previous | Thread Next
