As an example of why... I found this in io.ops :

I dislike replying to myself, however, it seems I haven't been clear
enough in describing how I think this (c|sh)ould be implemented.
Let's abstract DoD to the following psuedocode:
function markalive(p) {
if(!p.is_alive)
interpreter->dod_queue.enqueue(p);
}
for p in all

I would like for Parrot to have some way of creating Weak References; I
think that this is probably a vital feature.
The way I envision this is as follows. The following typedef and new
function would be added:
typedef void (*pobject_died_cb)(INTERP, PMC* who_asked,
Pobj* weakref, void *call

Not so much the string_* functions, but rather with how they work (the
encoding API, the transcoding functions).

Why would you want to remove a variable from a lexical pad?
Surely the "right thing to do" would be to create a new pad (scope),
then add your 'x' variable which

In the second chunk of the patch [classes/env.pmc], what is free_it set
to if the else branch is taken? IOW, I think you should have free_it
initialized to 0 when you declare it.
In the last part of the patch [config/gen/platform/win32.c], why do you
set *free_it to 0 even when you return NULL?

In pmc_new_noinit, I see a switch() which decides whether or not to do
add_pmc_ext. Why not have that information (whether or not an ext is
needed) defined in each of the .pmc files, and stuck in the vtable?
That would allow other cache-only pmcs to avoid getting an unnecessary

Having applied a bit more thought, having the generation field as part
of the PMC isn't all that great -- it makes PMCs larger, but it's really
only needed for new/neonate pmcs.
Instead of attatching the generation directly to the pmc, have a global
(per-interpreter) stack of neonate pmcs. Each

Actually, that (sometimes) should be able to be changed to:

What kind of semantics do we want for perl6, if we have:
my $fh1 = fdopen( $n );
do {
my $fh2 = fdopen( $n );
};
# is $fh1 valid or not at this point?
For that matter, what about:
for(1..2) {
my $fh = fdopen( $n ); # does this succed the second time?
}

#!/usr/local/bin/perl -wlpi.bak
s/
(\$?\w+) \s* -> \s* vtable \s* -> \s* (\w+) \s*
\( \s* (interp\w*) \s* , \s* \1 \s*,
/VTABLE_$2($3, $1,/xg;
__END__
[untested]
Then run it on all the code, except that which actually define
