Performance/Detect Cop and Enumerator::Lazy

[zapo]

Hi there. First, many thanks for the great work :)
Performance/Detect doesn't look to handle Enumerator::Lazy instances.

2.2.2 :001 > [1, 2, 3, 4, 5].lazy.select { i % 2 == 0 }.first(2) => [2, 4]

Not sure if this is known and/or planning in supporting it ?

One workaround is to take(n).to_a

My guess is that lazy was not considered when writing the cop. This sounds like a reasonable request to not register an offense when lazy is used. This is probably impacting Performance/Count as well. This should be pretty easy to implement.
