Good to know, thanks!
----------------------------------------
Bug #8801: Splatted assignment with Enumerator::Lazy
https://bugs.ruby-lang.org/issues/8801#change-41242

Author: benmoss (Ben Moss)
Status: Rejected
Priority: Normal
Assignee: 
Category: 
Target version: 
ruby -v: ruby 2.1.0dev (2013-08-18) [x86_64-darwin11.4.2]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


Actual:
>> a = [1,2,3].lazy
=> #<Enumerator::Lazy: [1, 2, 3]>
>> b, *c = a
=> #<Enumerator::Lazy: [1, 2, 3]>
>> b
=> #<Enumerator::Lazy: [1, 2, 3]>
>> c
=> []

Expected:
>> a = [1,2,3].lazy
=> #<Enumerator::Lazy: [1, 2, 3]>
>> b, *c = a
=> #<Enumerator::Lazy: [1, 2, 3]>
>> b
=> 1
>> c
=> [2, 3]

Basically, I expect a lazy array to act like a non-lazy one, and that using a destructuring assignment like this is basically the same as calling #take(1) and #drop(1).
