My Idea actually is to embedd that into the namespace syntax.
The idea is that of looking up non-negativ integer literals
with 0 beeing the namespace owner.
for ::Namespace -> $instance
{
if +$instance != 0 { reconfigure $instance }
}
Oh, so a namespace can behave as an array then. Well, to avoid
auto-flattening problems in other, more common places, we ought to
make that:
for *::Namespace -> $instance {...}
Well, even more huffmanized would be
for Namespace -> {...; use $_}
might be what you expect after
my @array = (0,1,2,3);
::Namespace ::= @array;
However, this is very huffmanly incorrect. First of all, what you're
doing may take a quarter of a second or more for a large program
(which isn't a short amount of time by any means). Second, the fact
that you're using it means you're doing something evil. Third, only a
fraction of 1/omega perl programmers will be using this feature.
Therefore, it should probably look like:
use introspection;
for introspection::ALL_INSTANCES(::Namespace) -> $instance {...}
This is why I wonder how writeable the namespace is, and when.
On some platforms it might actually not even be readable because
it was compiled away or stripped from the excecutable ;)
All that remains then is the possible behaviour as it is constrained
by the types of souls/daemons the creator happened to *choose*.
I guess you should re-read $Luke::Bible or watch the
$*::Movies::WarnerBrothers::Matrix again :))
If both refs are undef in your namespace, go and bind them!
If the above is insulting, feel free to invoke my &.apologize with
you as topic. You know, I'm the $/ of this $email.
And it might even be platform-specific, given the constraints of some
of our targets.
The platform is yet another restriction on Space::Search::Solution.
Interestingly namespace lookup is big endian...
