Printed	Page 24 3rd paragraph	The example is describing possible scoping issues that may occur. I've noticed a similar quirk in python, so I tried out the author's example, but it doesn't work as stated. ``` j = 7 (1..4).to_a.each { \| j \| } # j now equals 4 ``` The initializing of the local variable within the each block does not override the variable of the same name in the containing scope. In python this is the case, for example: ``` j = 7 for j in range(5): print("hi") """ j will equal 4 here """ ```	Anonymous	Jul 04, 2020
