How 'bout:
$foo = 'def';
$bar = 'ghi';
$y = 'abc$foo$bar';
$z = eval qq{$y};
Of course, for security and correctness reasons, you'd probably want
to:
$y =~ s/\\//g;
$y =~ s/!/\\/g;
Why would \\t not double-interpolate to a tab? Also, why would \\
not double

Just some thoughts in case you assumed people would only us Perl for
good.

Then you have ultimate control.
Uhm, I disagree. I think you really get ultimate control _without_
interpolate. Some people might want to make \\t interpolate to
By ultimate control, I meant that if you have an interpolate command,
you can then do whatever you want at each stage. You could do:
$z = interpolate interpolate $y;
Good point. Well, we were brainstorming macros for a reason ;). But an
efficient version would be nice, I suppose.

At a recent talk, Larry showed a line of code that was something like:
(@a; @b; @c) := (@x; @y; 1,2,3);
I'm curious about the mapping of @c to a list of constants; if I write
@c[0]++;
am I bumping the value of 1? As it happens, this used to be the case
on some old Fortrans that used

No. We've learnt that lesson, at least :-)
My understanding is that:

Of course, exactly the same thing is true for the English
You can do anything you like if you mess with the parser. Changing
the rules for recognizing an identifier would be trivial.
Does this refer to messing with the parser... compile time (that is, when
Perl compiles, not when Perl is compiled)? Or are you actually talking
about screwing with
Does one of these items not belong?
From Exegesis 4:
This new turbo-charged 'smart match' operator will also work on arrays, hashes and
lists:
if array =~ $elem {...}# true if array contains $elem
if $key =~ %hash {...} # true if %hash{$key}
if $value
So, here I am working on a Scheme interpreter in Perl 6, and I'm
trying to write it in a (for want of a better description)
'Scheme-like' fashion with lots of recursion.
The trouble is, unless Perl6 is going to be guaranteed to do
optimization of tail calls, this is going to lead to horribly

I just read Exegesis 4, and I have a few questions about private
variables. First, is it possible to have 2 private variables of the same
name in different functions? For instance, what would happen in the
following code?
sub func1() {
our $varname is private \\= 1;
return
