Hmm, it might not be a bad idea to make Interval a subtype of Range
and allow for iteration if that is requested. This allows an Interval
where Range is expected.

The benefit of a dedicated Interval type comes from supporting set
operations (&), (|) etc. which are still unmentioned in S03. BTW,
what does (1..^5).max return? I think it should be 4 because this
is the last value in the Range. Only in 4.7 ~~ 1..^5 does the five
matter. How does ~~ retrieve that information? For open intervals
the .min and .max methods should return the bound outside. Or better,
we should introduce infimum and supremum as .inf and .sup respectively.

Since the Interval type shall be an addition to the Set subsystem I
propose the (..) Interval creation operator together with the open
versions. Admittedly that leaves (^..^) at a lengthy six chars. But

Have set operations been implemented in either Rakudo or Pugs?

No offense, but I've noticed a tendency on your part to suggest highly
technical names for things.  "Infimum" and "supremum" may be
technically accurate; but I wouldn't know, since I don't know for
certain what they mean.  "Min" and "max" may be misleading in terms of
the specifics; but they get the general point across.

 	To further clarify, I put this exact question to Larry, and he 
basically said that the clarification of POD variables will happen as Damian 
continues work on S26-Documentation.

 	I vote in favour of the general idea, although I disagree with some 
aspects of this.  I think there are many things that could be grouped 
together, but I think we should be careful not to go too far.  Larry wanted to 
Huffmanise many of these too, hence the great number.  I think we could 
probably reduce the number by maybe 1/3.  If I get around to doing this before 
someone else does, I'll certainly refer to your groupings below for ideas.

Google's Summer of Code 2009

Google has announced this year's Summer of Code[1]. The Perl
Foundation accepted one project (mentored by Moritz) related to Perl 6
last year[2]. I was wondering if there are any developers interested
in mentoring students on Perl 6-related projects this year. I for one
would like to apply (as a student) for some Perl 6 work.

i'm glad your interest is building, based on last year's successes.
this year, the perl foundation will again apply as a mentoring
organization for google summer of code.  leading the effort will be
jonathan leto, one of last year's mentors, stepping up to fill eric
wilhelm's role as organization administrator.  like last year, tpf
will encourage applications for both perl 5 and perl 6 projects, and
parrot projects as well (as long as they're perl-related).

last year, if i recall correctly, 44 mentors applied for tpf, and 25
student applications were received (of which 16 met the tpf standard
for acceptance).  google allocated 6 slots to tpf, and 5 projects were
completed.  this year, i expect more organizations and more students
will apply, and i know both fewer organizations and fewer students
will be accepted into the program.  if the perl foundation is accepted
again (i have high hopes), you should know that the perl community is
extremely generous.  i have no doubt tpf will again see more
volunteers show interest in mentoring students than students
applicants, and i expect there will be many more project applications
than acceptances.

New Revision: 25651

Log:
S28:
-	Did more heading changes to make it "Special Names" instead of "Special	Variables"
-	Added lots of spec cross-references
-	Added a	$*DISTRO variable (hopefully this was just an omission)
-	Added a	SoftwarePackage	class that represents the name and version of the software 
        mentioned, whether this be Perl, and OS, or a Distro.
