Hi,

I need to find the number of entries in a directory, so I do this: 

opendir my $dh, $dir or die $!;
my $entries = grep {1} readdir $dh;

[download]
What bugs me is the "grep {1}"-thing that I do for the sole purpose of forcing a list-context on the readdir as doing simpy a $entries = scalar (readdir $dh) (i.e. putting paentheses around the call) does not do the trick...

So I wonder now: What is the idiomatic way to force list-context?

Many thanks!
