Question

I expect the following 2 prints are the same.

@a=(a..z);
print "@a\n";
print @a;

But actually, it gives me this:

a b c d e f g h i j k l m n o p q r s t u v w x y z
abcdefghijklmnopqrstuvwxyz

Why the extra spaces?

I am using ActivePerl for Windows.

Update

With the following 2 answers, I came up with this:

use English;
$LIST_SEPARATOR="*";
@a=(a..z);
print "@a\n";

And it gave me this:

a*b*c*d*e*f*g*h*i*j*k*l*m*n*o*p*q*r*s*t*u*v*w*x*y*z

Answer 1

Because the default value for $" is a space and the default value for $, is an empty string.

You can read about all of Perl’s special variables in perlvar.
