[MacRuby-devel] RubyCocoa layer

[Laurent Sansonetti]

It's because you subclass NSObject. Try subclassing Object, and it  
will work.

$ ./miniruby -ve "class Foo; def initialize; p 42; end; end;  
Foo.alloc.init"
MacRuby version 0.3 (ruby 1.9.0 2008-06-03) [universal-darwin9.0]
42

The machinery is implemented in Object.

# You should not subclass NSObject from MacRuby. An exception will  
probably be raised in the future.
