Iterators haven't been defined yet, so it's hard to tell.
For map and grep, it's certainly feasible, depending on their implementation
- although neither are truly iterators.
will the iterator variable be available in map, grep, join...etc...
I was also wondering if the join syntax be extended in a way that it can
support preffix and suffix... what i have in mind ... not necesary but :
#pair
join ($prefix => $suffix), @ary;
so :
my $select = join (qq{} => '
It's still largely incomplete, and getting a little weighty, so v.2 is up
on my web page:

I'm sure I didn't cover all the corrections from the first go round, so if I
missed anything, gently poke me in the side.
What's been added?

Okay, then I simply need to rethink/redefine how I'm defining a statement,
(which is currently in terms of the statement separator).

A few, hopefully relevant thoughts (some of them).

A thread from last July, WRT bug ID 2717.003 [1], suggested that we may
want to revisit the behavior of flow control expressions within the context
of a subroutine.
The current behavior is to find the closest (labelled) enclosing loop

hi,
As we read in Damian Conway- Perl6-notes, there will by a var-iterator that
can be used to see how many times the cycle has been "traversed" i.e.
foreach my $el (@ary) {
.. do something
print $#; <--- print the index (or print $i )
}
shall we have :
foreach my $el (@ary) {

A couple weeks ago I alluded that I was working on some documentation.
After a brief hiatus, I've picked it back up, and am ready to release
an entire half document. Big whoopee.
Anyway, what I'm working on is more or less a Statement of Fact, from a Perl
6 language perspective. It is in
