But the thing is, some newbie writes a script in the all new perl 7 and doesn't start it with the "use v7;" line. It works, everything is fine. A couple of years into the future, a new release of Perl with some incompatible changes is ready, perl 8. You follow the same logic: "use v8;" is not mandatory, new features are enabled by default and so, a good bunch of perl 7 scripts and modules become broken, and people is forced to change then adding a "use compact::perl7" line? It doesn't makes sense to me. It you want to avoid the "use v7;" line, then you should be able to tell perl explicitly in some way you want the 7 semantics. The only sane way I can see for that, is using different file terminations. I.e. p7, pl7, pm7, t7. And when perl 8 comes out, you can switch to p8, pl8, etc.Thread Previous | Thread Next
