in thread Real life uses for closures.

Anyway.... I've taken us way off topic. I apologize for rambling in your thread. :)

Actually, you haven't. The underlying motivation behind my asking the OP question was itself pretty off-topic -- though underlying that is very Perl-related -- and it is my belief that a truly modern (rather than a labeled-modern dialect), computer language like C++11 (or D2 or few others), is the future of Perl.

That is to say, I think that everything that is wrong with Perl5; and all the things that have gone wrong with the previous and ongoing attempts to implement Perl6; are firmly routed in the archaic programming languages and practices that have been and continue to be used to implement their infrastructure:

  • Using macros to force inlining -- whether beneficial or not -- instead of inline functions.
  • malloc & free rather than RAII;
  • The pile'em high, wherever-it-fits heap-based memory use.
  • Pointers instead of references;
  • Consting & copying rather than move semantics in an attempt to solve the shared state problem.
  • Emulating a register-rich cpu in software, atop inherently register-poor, stack-based hardware.
  • Non-reentrant libraries, non-PIC, and god-object context encapsulation.
  • Code that leaves the requirements of multi-threading to be retrofitted as an afterthought.

Until and unless truly modern coding practices are used to (re-)construct the infrastructure required to support dynamic languages -- Perl et.al. -- they will surely become less and less relevant in a modern world.

So far from off-topic rambling, your bringing up C++11 was right on-topic for the thought processes that led to this thread. Thank you.

[Cosmic37]: I'm wondering whether there is a specific/(or at least "usual") command or does one take a copy before undefining and then copy it back after slurping file into a string?
[BarApp]: I need help accessing perl files. I need permission!!!
[Cosmic37]: I wish thee a peachy life and express gratitude for considering my pathetic questions
[erix]: record separator
[Cosmic37]: Permissions are interesting earthlings. Did nature determine who gives permission and who asks permission. Who was the first to get permission? Are you not related to them as one big earthling family?
