  Thank you for submitting those pull requests.

  This is just normal Perl 5 behavior, although your need v5.16 or later for CORE.

  Here's a demonstration that we build up in [Intermediate Perl](https://www.intermediateperl.com/) (and as a gist where I might expand this). The problem is that the arrow operator is under documented in perlop.

  #!/usr/bin/perl
  
  {
  
  package Parent;
  
  sub bar { print "Parent: $_[0]" . "\n" }…

  As for the pipe operator part of this post, the arrow is not going to do that. A proper pipe operator would feed all of the values from the left hand side to the right hand argument list. The arrow isn't going to do that.

• Brett Estrade commented on A pipe operator exists on perl v5.42?

  A pipe operator would be good and totally consistent with Perl relationship with unix. You want to check out my Sub::Genius module, which allows you do this using concurrent semantics. There are other modules that do this kind of thing, but as far as I know the concurrent semantics are unique to Sub::Genius. I gave a talk on it when everyone was hiding from covid and we didn't have a Perl conference. The drawback of course is it's "plan" based and not code based like what you're suggesting. I still like it.
