in reply to inheritance: constructors

This is why you ought to use Moose, or a Moose-work-alike such as Moo for pretty much any OO. You never need to write another constructor again!

use v5.14; use strict; use warnings; package Word { use Moo; has stem => (is => 'ro'); has english => (is => 'ro'); } package Noun { use Moo; extends 'Word'; has gender => (is => 'ro'); has nom_sg => (is => 'ro'); has gen_sg => (is => 'ro'); } my $w = Noun->new( stem => 'ai(=m-', english => 'blood', gender => 'n', nom_sg => 'a', gen_sg => 'atos', ); say $w->english;
perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

[Corion]: Discipulus: Well, in many cases it doesn't make sense to build an interface and complicated program just to enter 20 rows into a database ;) But yes, automating data imports should pay off in the long run
[LanX]: Choroba: this happened before I joined, was still in uni, but my boss was summoned to the CEO of the second biggest German bank at that time and could only say " I told them its not ready" ;)
[LanX]: memories....I missed my connection while chatting
[Discipulus]: in this case Corion we are speaking about software licensing: evry year or two we must rescan the whole ced to produce an excel report, while at every activation / disactivation we update a black box DB: i said that i a week i can produce the perl to..
[Discipulus]: rend out the xls IF i have access to the DB
[choroba]: LanX I miss working in a bank sometimes...
[Corion]: Discipulus: Ooof. Especially yearly things are things I like to automate instead of trying to remember how I did things last year...
[Corion]: And the second rule that I've learned is, that there is no one-off job, so writing a program for it pays off almost immediately. The third rule is to give all my programs numbers and have them reproduce that number in the name of their output files. :)
[Discipulus]: the true part is that also specification change between years.. but well our job is cheap but dont abuse of us.. ;=)
