warning: default `to_a' will be obsolete

[David Corbin]

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?

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.

Use [*foo].

That doesn't really look much clearer to me...

Array( foo )

Same effect.

Array( foo )

Array[ foo ]

[Yuri Kozlov]

and in the 1.9.0 it is already happens
irb(main):001:0> x = 1
=> 1
irb(main):002:0> x.to_a
NoMethodError: undefined method `to_a' for 1:Fixnum
from (irb):2
irb(main):003:0>

 

[Markus Koenig]

Array( foo )

Array[ foo ]

Not quite the same:

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