Cons: * Rakudo -- the only P6 compiler for now (and likely many years, maybe forever) -- has a slow startup, around 0.1 seconds or so. * Rakudo is still a work in progress. What's done is pretty solid but, for example, no one has imple

The default rational type isn't unlimited precision. See my comment at https://www.reddit.com/r/perl/comments/93dabg/perl_6_small_s... for an explanation and demonstration of P6's approach.

Thanks for the 2017 link. Its NQP that does metacompilation, not MoarVM (afaik). I linked to NQP's (spartan) readme above. Some other points/links that might be helpful: * nqp is written in nqp. * nqp has a first class grammar con

Thanks for replying. I think MoarVM/NQP are strikingly similar in their approach based on what I've learned so far about Graal/Truffle (which isn't much; perhaps a few hours of exploration; eg reading/watching the O

The Perl 6 Inline::Perl5 automatically maps Perl 5's syntax, object system semantics, exceptions, etc. to Perl 6's so that Perl 6 users don't in principle have to know about Perl 5, just the logical API of any used module&#x2

There have been two such breaks, not one. Perls 1-5 correspond to the first such break. Perl 6 corresponds to the second. If "regular expressions" is taken to refer to formal language theory regular expressions -- which is NOT w

Stefan Seifert authored or maintains both the P5 and P6 versions of Inline::Python, the Inline::Perl5 for P6 and the Inline::Perl6 for P5. Three of the four are at the first stage. They work in much the same way, using `.run( ... )` to run

To begin to transfer P6 grammar/parsing features or techniques to another language you'd have to bundle NQP and one of its backends. Does that sound worthwhile? Also, how would you handle strings in this other language? In P6 and

One of the bigger features of P6 is that it can use modules written in other languages such as python.[1] Are you aware of the compatibility with Perl 5 that I mentioned in my prior comment in this thread? If so, why do you discount it? [1]

If you browse the #perl6-toolchain logs[1] you'll see folk making steady progress toward practical interop of multiple versions of the P6 language (6.c, 6.d, etc.), P6 compilers (Rakudo 2017.07 etc.), and P6 modules on the one hand and

Do you consider Haskell to already be extremely successful? (Haskell planning began in 1987, the same year Perl 1 shipped.)

Why does Python have other options if no one is using them? Are these other options cruft in the language design, the compiler, or just reasonable support for features intended for other, perhaps infrequent, usage? The old P5 motto TIMTOWTD
