What should be the exact output? In Ruby 1.9.1, I see the following output:
$ ruby test.rb
"A"
"B"
"C"
"D"
Note: When <class>.new is called allocate method is called. Then the
object's initialize method is called and the
instance is returned to the caller.
$ macruby test.rb
"HasInit"
"A"
"HasInit"
"B"
"C"
Segmentation fault
Now, changing the init methods to initialize, the following output is
generated:
$ ruby test.rb
"HasInit"
"A"
"HasInit"
"B"
"C"
"D"
$ macruby test.rb
"HasInit"
"A"
"HasInit"
"B"
"C"
"D"
Next, will there be an implementation of BasicObject in MacRuby as it is in
Ruby 1.9.x?
