I'm not entirely sure you've illustrated that it's a bad idea. I believe that I illustrated that a simple pattern is not easily doable in Python but is in Perl 6. You'll have to show that this is a bad pattern or the imp

You might be a little confused, I'm pretty sure that wantarray and the concept of functions caring about context is entirely gone in Perl 6. Now you are expected to return objects which 'do the right thing'. However, if you r

Could you explain why you think this is awful? Perl 6 has proper sets, bags and the appropriate operators for 'normal' set operations too.

Sorry I should have made things more clear. I am talking about in things like function signatures. Doing something like isinstance(x, str) is discouraged and considered non-pythonic, and recently hasattr() has also been talked about. Howeve

It's not so much SIMD. Perl 6 has a number of different constructs in which multiple operations can be carried out like that. However, yes the intention is to enable a large number of these scenarios to be carried out on multiple CPUs.

Please point out a critique of the language in this thread.

> Why not "if 5 < x < 100"? Sigils look awful. Because sigils tell you things. What if 'x' in your example is a list? Are you now checking the length of the list rather than the value? Sounds like room for a sec

It's not standard sets, it's a bit more than that, Perl 6 has sets of course, but Junctions should be able to autothread and express a sort of superposition of values. http://doc.perl6.org/type/Junction I cou

I too have been admiring Jnthn's latest posts. The reactive programming displayed is really quite lovely. God it actually makes me want to develop an asynchronous client! The only other language that makes me feel that way is Go.

Perl is pretty concise, but the list of criticisms above are almost meaningless. Who releases the first version of a language with most of the time spent on the optimiser? Perl 6 loses quite a bit of the Write Only type syntax, and should b

I'm sure you're right, the REPL uses Linenoise which is single byte character only for example. The only way to fix these problems though is to increase their use, so ultimately the end goal will be worth it. That seems to have be

I've seen some complaints about this, but the existence of Texas versions of the operators makes this absolutely fine in my eyes. I don't see why people would begrudge the ability to use the 'proper' mathematical symbols

Perl6 is actually ROAST, but Rakudo is the first compiler that approaches implementing it. Parrot was unfortunately discontinued but Rakudo will not be the only compiler (hopefully!)

There are ASCII equivs for most, they're called 'Texas' operators.
