REPL Improvement Goals

Not necessarily in order of importance or ease of implementation!

• Specify which line editor is preferred
• Don't prompt user about Linenoise on Windows
• Be able to turn off Linenoise/Readline/rlwrap hint
• Suppress Linenoise/Readline/rlwrap hint if running under rlwrap
• Persistent history
• Multi-line input

Strange Loop talk proposal -- due 2016-05-09
http://thestrangeloop.com/cfp.html

Title: Rakudo/Perl6, The Polyglot Langauge

Abstract (max 1500 chars)
========

Taking multi-paradigm to a new level, Perl 6 goes far beyond it's Perl 5 roots, adopting concepts from many languages. From Haskell/Elixir style typed multi-dispatch to Ruby style objects-all-the-way-down, you can pick a model that best fits your problem domain. Add to this some very practical innovations, such as a grammar engine and native stream/promise async/concurrency, and you have both a useful tool and an interesting experimention platform. The production-ready Rakudo implementation of Perl 6 targets both it's own MoarVM and the JVM, and a JS target is in progress!
