You can use $_ and @_ AFAIK

    They are different. You can run the following example.

    The part below the __DATA__ shows the expected output: $VAR1 is $_, $VAR2 is @_
    (the \ in the Dumper statement is to have @_ formatted as array rather than individual scalars).

    Before you go hunting for that odd Perl version: it specifies the minimum version. If your Perl is even older, you can change use 5.011 to use strict and say by print.

    #!/usr/bin/env perl use 5.011; # implies strict + feature 'say' use warnings; use Data::Dumper; for (1 .. 2) { say "in loop:"; say Dumper $_; test(3, 4); } sub test { say "in sub:"; # $VAR1 $VAR2 say Dumper $_, \@_; } __DATA__ in loop: $VAR1 = 1; in sub: $VAR1 = 1; $VAR2 = [ 3, 4 ]; in loop: $VAR1 = 2; in sub: $VAR1 = 2; $VAR2 = [ 3, 4 ]; ];

    No and yes, respectively.
