Class and Object Components
Class component: shared by all instances
Object component: unique for each instance
Could use a global variable...
var shared_count = 0;
function z()
{
var count = 0;
shared_count += 1;
count += 1;
this;
}
function x()
{
extends(z());
}
inspect(x() . shared_count);
inspect(x() . count);
inspect(x() . shared_count);
Results are as expected:
x() . shared_count is 1
x() . count is 1
x() . shared_count is 3
Not very satisfying...
