Re: [Omaha.pm] my $a = blah();

[Andy Lester <andy@petdance.com>]

$ cat j.pl

my $a = blah();

print "$a\n";

sub blah {

   return (7,8);

}

$ perl j.pl

8

Perl knows that blah() is being called in scalar context, so it evaluates (7,8) in scalar context, which is 8, because it's the rightmost value after the comma.

Now, if you'd said

my ($a) = blah();

then $a will be 7, and 8 gets ignored.
