I'm getting this warning, which I think is new in 1.8.3.

warning: default `to_a' will be obsolete

However, I can't find what the expected alternative is.  Any pointers?

David

Object#to_a from ri:

 Returns an array representation of _obj_. For objects of class
 +Object+ and others that don't explicitly override the method, the
 return value is an array containing +self+. However, this latter
 behavior will soon be obsolete.

so it's this "return array containing self" that's going obsolete.

But it doesn't hurt duck-typing.

Not quite the same:

  foo = [1, 2, 3]
  Array(foo)        => [1, 2, 3]
  Array[foo]        => [[1, 2, 3]]
