Any other way to do this

[Radhakrishnan Venkataraman]

Please see the following script that checks for type and sums up only the
numbers passed as arguments to the script in the command line.  I would be
grateful if any improvement or furtherance to this script is offered.
Thank you.

#
# sums the numbers given in command line arguments and prints
#
my $sum = 0;
for @*ARGS
{
$sum += $_.Rat if $_.Int // 0 !=== 0;
}
say $sum;
