Perl6 also has been able to do this for a couple of years: sub fib(Int $n) { return $n if $n < 2; my $t = start { fib($n - 2) } fib($n - 1) + await($t); }

As far as I'm aware, here in DE they have to take such large notes as long as it's proportionate to the sum owed. Coincidentally, Germans do love their paper money more than most.

By that time, Amazon for example had already decided that Perl's time had passed. Another case in point, look at the Google trend for "perl tutorial"[1]. Unfortunately, that only starts at 2004, but you can still see by that

It's a trade-off, though: Compactness and visual variety can help readability. There's a reason why symbolic math notation won out, and why the most regular and/or verbal languages (eg Lisp, Cobol) haven't won over every

Perl6 was a reaction to Perl5's loss of mindshare, but it took a very long time to arrive and still cannot be used as a drop-in replacement for the latter. It has rather different strengths and weaknesses and thus has to find a new nic

The thing is, Perl6 as it exists today can not be used as a replacement for Perl5, and in consequence, Perl5 development continues and will continue for the forseeable future. It's better to think of Perl5 and Perl6 as two separate lan

You hear such complaints a lot, but frankly, this has never been an issue for me in practice.

Depends: Some things can still be really (and I mean really ) slow. For example, I've been complaining about the speed of the regex/grammar engine for years. On the upside, the parallelism story is better than Python's or Pe

Those are probably mostly Perl5 people, though.

For the record, this could also be written as (1..100).hyper.map(&f).reduce(&g) Syntactic sugar can make a mess when overused, but also improve readabiliy tremendously when used judiciously.

Perl6 has had two proper language releases (v6.c in Dec 2015 and v6.d in Nov 2018), and there's a compiler that implements them (namely Rakudo). The language is not 'finished' insofar that parts of the original design have ye

There are various studies on the topic. For Germany, the figures that stuck in my brain were these: We can go 60% renewable without much of a problem, 80% with strategic storage and significant grid improvements, 100% via off-shore windpark

It also took quite a while for people to come up with the concept of universal human rights, we're still bad at overcoming tribalism, and basing morality on majority vote isn't necessarily the best idea. That aside, you're ri

The latter, presumably: Culling humanity for its own good is generally considered immoral, while it is deemed acceptable in case of nonhuman animals. That mismatch requires justification.

The increase in Germany was only temporary, though. We hit a low point in '09, and a high point in '13 (but still below levels of '07). Coal usage has gone down ever since, and we're currently at a new low.

Naively, replacing coal with gas will decrease CO2 emissions by 40%. Not sure how this changes once you factor in supply chains, etc.
