Simple question on some code that I've been looking at (in this case:
Component::Server::TCP ).
Is there a good reason for doing the following:
my $var = delete $param{Fld};
I see this a lot when parsing the input args and am trying to figure out any
advantage of doing the delete over just an assignment (ie: $var =
$param{Fld} )
example:
# Extract parameters.
my $alias = delete $param{Alias};
my $address = delete $param{Address};
my $port = delete $param{Port};
my $domain = delete $param{Domain};
thx,
bobm
