warning: redefining Object#initialize may cause infinite loop

[Trans]

irb(main):001:1class Object
irb(main):002:1> alias :init :initialize
irb(main):003:1> def initialize( *args, &blk )
irb(main):004:2> init( *args, &blk )
irb(main):005:2> end
irb(main):006:1> end
(irb):3: warning: redefining Object#initialize may cause infinite loop

Is this warning really neccessary?

Thanks,
T.

No, and I'd like to reiterate my idea for structured warnings so that
we can wrap and disable them as we like.

Object#initialize is too broad. If you allocate anything that calls
Object#initialize it would turned out to be infinite loop which is
definitely not expected at all. I was surprised when I met it.

That doesn't matter: POLS only means Matz's surprise. Oh, wait....
