    Example, all oneliners :D
    $ perl -c -e " use strict; use warnings; BEGIN { $sumeet = 1; } $grove +r = 1; } " Global symbol "$sumeet" requires explicit package name at -e line 1. BEGIN not safe after errors--compilation aborted at -e line 1. $ perl -c -e " use strict; use warnings; BEGIN { our $sumeet = 1; } $g +rover = 1; } " Global symbol "$grover" requires explicit package name at -e line 1. Unmatched right curly bracket at -e line 1, at end of line syntax error at -e line 1, near "; }" -e had compilation errors. $ perl -c -e " use strict; use warnings; BEGIN { our $sumeet = 1; } $g +rover = 1; " Global symbol "$grover" requires explicit package name at -e line 1. -e had compilation errors. $ perl -c -e " use strict; use warnings; BEGIN { our $sumeet = 1; } ou +r $grover = 1; " -e syntax OK

    Agreed, compilation would be based on statements, separated by semicolon!

      We don't need no stinkin semicolons !:)

      $ perl -c -e " use strict; use warnings; { $foo = 1 } { $bar }} " Global symbol "$foo" requires explicit package name at -e line 1. Global symbol "$bar" requires explicit package name at -e line 1. Unmatched right curly bracket at -e line 1, at end of line syntax error at -e line 1, near "}}" -e had compilation errors.
      $ perl -e " use strict; use warnings; { our $foo = 1 } { our $bar } p +rint 666" 666

        Well, I certainly do prefer using semicolons, having first learned C programming. I also regard using semi colons at the end of programming statements to be a good programming / software-development practice.
