Range does Iterator so it is already discrete and totally ordered.
So the interesting class to derive is probably BoundedRange.

Hi,
the attached patch modifying HLLCompiler.pir supports parsing from an
arbitrary rule in a grammar, using the $:rule parameter
Example :
grammar A { token a { a } }; say A.parse('a', :rule).perl
This is nice for testing part of a grammar.
This patch is the result of the following conversat
When doing an analyse of a sample parse tree, I note that it is
cluttered by the reduction of optional subrules
to generate a zero length parse subtree. That is, rules with a '?'
quantifier matching zero time.
Suppressing such matching rules from the parse tree would make it
easier to read.

Giving scoping functions the status of list operators

I expect Perl6 to be a language with a mix of dynamically typed and
statically typed variables. In a purely statically typed language like
OCAML, you generally don't need to declare the type of variables
when it can be inferred. So one can benefit from the speed of static
typing (no type info must

You are considering read-ony PMC versus others. Another issue
is properties. Many PMCs "classes" will support properties that will
alter their behavior. But most PMC instances will have no property
attached to them. Or just default values of them if you see it that
way.
To avoid to go back the sl

I use over and over this idiom in perl5:
$a{$_}++ for @a;
This is nice and perlish but it gets easily pretty boring
when dealing with many list/arrays and counting hashes.
I thought overloading the += operator
%a += @a;
Probably that operator should be smart enough to be fed with
a mixed

I have confused assignement and initialisation in my previous
mail. Because they are two different operations, there is no
problem they have different semantics. A6 described both
operations. It described pairs as arguments used to initialize
parameters and pairs in assignement.

My understanding of the semantic of pairs as in A6:
A pair in a given scalar context should return its first element
coerced to match the said context.
This seems to be a prerequisite to use pairs as function arguments.
Example with the boolean context:
bool $b = a => 10; # $b == 1

Hi,
I am writing a PerlPair PMC and I have a problem with an
optimization. BTW: probably a modified PerlPair could be used
to implement lisp cons pairs and the optimization will be even
more useful because of the widespread use of pairs.
The optimization: I want to avoid storing a key or or value

The get_*_keyed methods were missing from PerlArray. Inheriting from Array did not
cut it when accessing elements beyond the array end.
The patch adds the missing methods. They really are a cut and paste
from the Array methods. They access the corresponding get_*_keyed_int() methods,
or the get_p
The implementation of the methods key_* in keys.c imposed
to the PMCs to be of type Key. I don't' see the interest
for atomic keys that could be mere PMCs.
This concretely means that one can write the following and save a
intermediate register:
P3 = PO[P1]
instead of:
P3 = new P2, .Key
