contributed this to our collective wisdom:
(really beginners) could think "@a" will empty array, which is not
true.
JN> yes it is true, they are both empty lists:
@a will not empty array, here it is:
my @a = q{foo bar};
@a;
print @a;
against
my @a = q{foo bar};
@a = ( );
print @a;
I hope you see the difference :)
And you would as well if you had warnings enabled as the first example would
warn you about using an array in void context.
$ perl -le'
use warnings;
my @a = qw{foo bar};
@a;
print @a;
'
Useless use of private array in void context at -e line 3.
