Localizing a variable (and yes, I want local, not my) defined in a different package yields strange results: 
#######################
package A;
our $variable = 3;

#######################
package main;

{ # I want to localize the variable in this block
  local $A::variable;
  print "$A::variable\n";
}
print "$A::variable\n";

The first print complains about an uninitialized value, while the second one prints the previously assigned value. Or, more generally speaking, how come that 
package B;
local $A::variable;

[download]
undefs $A::variable?
