there is some seriously black art happening here:
i added the following code to callbacks.rb
def self.append_features(base) #:nodoc:
super
$i ||= 0
p $i
p caller.last
$i += 1
...
...
...
and then fired up ./script/console. this is what it prints:
harp:~/ror/bug > ./script/console
0
"./script/console:2"
Loading development environment.
0
"/home/ahoward/bin/irb:13"
...
how on earth is that possible!? what has been done? just to illustrate it
would be as if this code:
harp:~/ror/bug > cat a.rb
module M
def self::append_features other
$i ||= 0
p $i
p caller.last
$i += 1
end
end
class C
include M
include M
end
printed out '0' and then '0' but, of course, it does not:
harp:~/ror/bug > irb -r a.rb
0
"/home/ahoward/bin/irb:13"
1
"/home/ahoward/bin/irb:13"
can someone shed some light on this?
