Dear Masters,
I have to arrays. One is larger than the other, and the smaller one is the subset.
Now what I want to do is to remove the elements in the larger array based on that smaller one.
Something like:
perl -MData::Dumper -e '
@ar1 = qw( a b c d e ); 
@sl =  qw( b d ); 
@ar2 = @ar1[@sl]; 
print Dumper \@ar2;'

Now from that code I expect it to return 
$VAR1 = [
          'a',
          'c',
          'e'
        ];

[download]
But it doesn't. What's wrong with it? And is there a quicker/better way to do it?
