in thread I usually debug via...

Generally a good approach, except that my programs are large and that could turn on hundreds of warnings. For me, I generally just need to turn on a few warnings at any given time and it's no big deal to hop around to those four or five that I've unmasked to comment them back up.

    My code is usually littered with stuff like print "Foo: ".Dumper(\$foo) if $debug>7;

    Often I write those in not knowing if I'll ever want that level of verbosity; usually I never have to crank $debug higher than 2 or 3. (1 just prints progress info usually, depending on what the app is; 2 gives more detail, and so on. 0 only prints actual errors, and undef suppresses non-fatal errors. Anything past 5 is dumping lots of big data structures.) Occasionally I do end up cranking it way up, though, and adding in extra print statements like the above, that I didn't originally anticipate needing.

[Discipulus]: Corion are you would able to realize such thing? O_O
[Corion]: In the same vein I have a script that automates Firefox to enter some data into another system. It's not faster than the people using the script if they were to do it manually, but they prefer not having to check the data and not having typos when ...
[Corion]: ... entering the data
[Corion]: Discipulus: I don't know whether I could really do that, but the init process itself mostly launches other processes, and the whole startup is just following a path of dependencies and making sure they are all running. Which basically is what ...
[Discipulus]: when at work my time is (temporarly) owned by the firm, so i do not care (coworkers whatch movies.. I code Perl)
[Corion]: ... make already does, except for files instead of programs. But maybe with some /proc hackery, that could be eliminated and one could use plain make :-D
[choroba]: systemd just makes is asynchronous
[choroba]: so, make -j
[Corion]: Discipulus: Yeah - but when writing Perl to save time (instead of having fun), it helps to look whether you're actually saving time ;) Why spend 5 minutes doing manually what you can spend three years automating? ;)
[Corion]: choroba: Oh, yeah :-D
