    Thanks Dean! I would like to say it has been a nice adventure, even if it could not be as simple as it sounds to write a whole book from scratch even if you know (or think to know) the...

  • Posted CPAN Pull Request: a little patch for January (and a lot more to learn!) to Luca Ferrari

    So I've done a very little (and to some extent very monkey-typing) patch for January.
    The story of my first fail is here, and a little summary of what has been merge…

  • Posted Reading about Perl to Luca Ferrari

    I like to read at least a computer book every 2-3 months, that makes around six books per year. This year was a very unluky one for me, due to family and personal wealth problems and surgeries. However I'm back on the rail of reading computers book again, and Perl is the predominant one this…

  • Commented on About one-liners
    Shell as glue for Perl...nice! I always thought Perl was the glue for all the other stuff. Besides, I agree, maybe living within my editor made me think the more about stand-alone scripts than one liners. Again, I see the...
  • Posted About one-liners to Luca Ferrari

    It's not that I don't see the utility for one-liners, it's just my own mindset that seems to prevent me to use them.
    On one hand, I often explain to other (non-Perl) developers how useful can be a one liner, but on the other hand I tend not to use them even when I could.

  • Commented on mop minus proposal
    While I appreciate the effort, I cannot understand why another OOP support when there already a lot, and with a very good implementation (Moose being probably the most adopted)....
  • Commented on What prevent warnings pragma become default feature?
    If retro compatibility is not an issue, I suspect that Perl developers would have already enabled warnings by default. On the same line of thoughts, why is not "my" a default for variables? Why not automatically using a predefined set...

    There's no reason you can have it both ways (at least in some respect).

    You can put your shell history in a git repository (true, this is not the same thing as putting a single script file).

    You can use an editor to edit command-line, e.g. C-x C-e.

    You can use something like M-x shell in Emacs, then later on save the whole session in a file (in a git repo) to document things, it even shows you the evolution of building up a working one-liner *with* the outputs.

    You can put your good one-liners in a script later (just chuck it in a file and prefix it with #!/bi…
