I'm posting this as an obfu, but it might well be a SOPW. I ran into it the hard way. My test was passing an IP address - 8.8.8.8 - to a sub in the intended module. The test was failing. When I looked at the value of the param in the sub with Data::Dumper, I got 8.8.8.8, but when I printed the param, nothing appeared. I was wasting time looking at my sub when I should have been looking at the test. I had left out the quotes around the IP address.
I know what my code is doing. What I don't know is why. This construct certainly doesn't DWIM and I can't see why it should be what anyone else would mean. Is there a sensible explanation? And let me add my usual question - is this documented anywhere?
Regards,
John Davies

Hello! Here is my JAPH. Not very cryptic, I just want to say it:
#!/usr/bin/env perl
use 5.026.1;
no strict;

BEGIN { use SelfLoader;
open *q, v60 , $0; s(.*)((<q>)[-1])e;

Stamp puzzle solution

Someone posted this challenge at work..
The country of Elbonia is standardizing its postal system to streamline its parcel service. All parcel boxes (many sizes available) now come with 10 preprinted rectangles on one side for stamps to be stuck into. Elbonia's stamp denominations are:
1c, 2c, 3c, 4c, 5c, 10c, 24c, 37c, 39c, 41c, 48c, 60c, 63c, 70c, 75c, 80c, 83c, 84c, 87c, $1, $3.85, $4.05, $4.60, $5, $14.40
Given an infinite supply of each denomination, what is the minimum postage amount that would REQUIRE 11 stamps and so not work with the streamlined service?
