I'm glad Ruby takes community feedback seriously, for the most part - most recently the pipeline operator and the named block parameters, for instance.

I heard Matz is going to remove the Perl special variables in Ruby 3.0. Can't think what the fuss is all about. They're pretty useful in command-line Ruby. I moved from Perl to Ruby so I will be sad to see this bit of Perl heritage removed from Ruby. I mean for what gain?

Only a very small subset of them: https://bugs.ruby-lang.org/issues/14240

    $/    input record separator (default argument for "gets")
    $\    output record separator ("print" prints it at last)
    $,    default separator for Array#join and print
    $;    default separator for String#split

As for the gain it's because these variables globally change the behavior of important core methods. They really aren't that useful, but can easily cause havoc.

Interesting. The discussion, although minimal, lasted years, then closed pretty quickly. Good for Ruby :-)
