Re: S5 updated

ok, cool, I'm beginning to understand perl6 patterns a bit better. Just a tiny request though (and I seem to remember this being discussed) - I wish that there was an easy syntax to turn regexes ...

Still about subroutines...

Speaking of subs, and especially recursive ones which have been mentioned en passant earlier, I have another question "of mine": I know that in the vast majority of cases this won't be useful in any ...

But is it intuitive?

I was thinking about removing files this morning, and realized that I wish rm supported inclusion/exclusion. In particular, I wanted to remove "* but not Makefile" (since my Makefile uses ...

S5: range quantifier woes

The new range quantifier syntax has been bothering me. For reference, here's the bit of S5 that talks about it: Now for the bothersome parts and some questions and some suggestions in no particular ...

This Week's Summary

NB: The links are probably broken at present. Normal service will hopefully be resumed once Google gets caught up with the perl6 lists. The Perl 6 Summary for the week ending 2004-08-27 Where does ...

How would I do this in Perl6? #1

Dear all, I've recently thought of a possible syntax extension for (Perl5's) [un]pack() and I posted my "RFC" to clpmisc where it didn't have much success, I must say. However I'm not interested in ...

Reverse .. operator

In perl 6, the statement @foo = (1.. 5) ; is equivalent to @foo = (1, 2, 3, 4, 5); Is there similar shorthand to set @foo = (5, 3, 3, 2, 1) ? I know you can go @foo = reverse (1 ..5); but this has ...

Q: re C<< -> >>

I hope not to raise too much the noise/signal level on list, but I have a question: I have had a long experience programming my HP28s pocket calculator, and its RPN language that AFAIK is mostly the ...

S5: grammar compositions

I was rereading S5, and the example of grammatical inheritance caught my eye: grammar Letter { rule greet :w { [Hi|Hey|Yo] $to:=(\S+?) , $$} ... } grammar FormalLetter is Letter { rule greet :w { ...

A question about attribute functions

How do you declare attribute functions? Specifically, I was thinking about map and what kind of object it would return, and I stumbled on a confusing point: class mapper does iterator { has ...

[S5] Topicalization of match

I've read S5, and hopefully I've understood the new $<digit -mechanism, that BTW seems very good to me. Only I have a suggestion that I hope not to be too awkward. Why isn't matched text aliesed to ...

attributes/methods on sigils?

I fear, and with good reasons, that this may be too wild a case of an extremization, but I wonder wether, just like for example strings are implemented by means of special (quote-like) operators, ...

S5 and overlap

Maybe I'm wrong here, but I'd get $str = "abracadabra"; bracadabr cadabr dabr br (so far identical), but then I'd also expect bracad cad d brac c br which gets me to the question, if there'll be some ...

[S3, S4, S5]: =~ becomes ~~

I know that, you know that ... but the synopses never actually say it. It's evident from context, but it's never said explicitly. I would *think* that should be in the "Operator renaming" section of ...

Unary dot and custom control

I came across this slight annoyance working in Perl 5 today: sub preserve(&) {...} sub foo { preserve { $_[0]- bar; } } That didn't call "bar" on the invocant of "foo", but rather on "undef", because ...

S5: array interpolation

Like this? (Assuming single quotes don't interpolate @foo[...]) @a = ('a', 'b', 'c'); '@a[0]' ~~ m:/ @a /; # true '@a[2]' ~~ m:/ @a /; # true '@a[9]' ~~ m:/ @a /; # false If so, that seems pretty ...

sub signatures without parens?

for, while, given, loop, etcetera can all be used without parens. Are the parens around the parameter specification still required? If so, why? In other languages it may make sense because parens are ...

Re: Why lexical pads

A mildly interesting thought would be for C<eval to take additional parameters to make explicit what's visible to the eval'd code--essentially making the running of the code like a subroutine call. ...

Why do rules match against strings?

Pardon if this has already come up. I only found one prior reference in my search. There's a section in S5 about "Matching against non-strings", but it really only addresses matching against strings ...
