Bug #9723
closed#size does not trigger evaluation of lazy enumerator.
Description
Here is the code which shows weird behariour
Steps to reproduce¶
$ irb 2.1.1 :001 > [1, 2, 3].lazy.select{ |e| e%2 == 1}.size => nil 2.1.1 :002 > [1, 2, 3].lazy.select{ |e| e%2 == 1}.to_a => [1, 3] 2.1.1 :003 > [1, 2, 3].lazy.size => 3
Expected¶
[1, 2, 3].lazy.select{ |e| e%2 == 1}.size
to return number of elements like [1, 2, 3].lazy.size
did.
Actual¶
[1, 2, 3].lazy.select{ |e| e%2 == 1}.size
returns nil.
