I agree with you on one level. That is enough to m

"X" is meaning "is in context". Sorry if that is misleading, I'll update
the pod.

Its not specified yet, how eval fits into the picture.

Is this supposed to happen?
% parrot -
.sub _main
$S0 = "Hello\n"
$S1 = $S0
substr $S1, 2, 2, ""
print $S0
print $S1
end
.end

Heo

Aren't strings supposed to follow value semantics?

The following program segfaults when run under JIT.
.sub _main
newsub P0, .Sub, _echo
$S0 = "abcdefghij"
savetop
restoretop
end
.end
.sub _echo
print P5
invoke P1
.end

Bug confirmed here (although I need a slightly longer string to trigger
it). Here's a stacktrace:

Q1: Suppose I have the following call into a sub named "foo":
foo($var1, $var2, $var3);
What should I set in I1? Is it 3?
And here:
foo($var1, @arr2, %hash3);
Is it still 3, since these aren't gonna be flattened?
Q2: I'm calling without prototyping
foo($var1, $var2, $var3, ... , $var23);

Considering that parrot is now emitting an executable (on some
platforms)... and IIRC, C will be one of the languages we plan to have
parrot support for... will parrot be able to compile itself? :)

I was recently reading the following:
http://www.parrotcode.org/docs/dev/infant.dev.html
It's missing some things. One of which is the (currently used?) way of
preventing infant mortality: anchor right away, or else turn off DoD
until the new object isn't needed.

Hey all,
Python objects can have things "in" them:
foo["x"] = "in"
... and it can also have things "on" them:
foo.x = "on"
I noticed lua treats these as the same thing
and got curious about the distinction in IMCC.
Coding it this way seems to work, but I'm
not sure I really understood t
