PS (2) > $foo = @{　　>> a = 1
　　>> b = 2
　　>> c = 3
　　>> }
　　>>
　　PS (3) > $foo
　　Key Value
　　--- -----
　　a 1
　　b 2
　　c 3
　　Now assign $foo to $bar and verify that it matches $foo as we expect.
　　PS (4) > $bar = $foo
　　PS (5) > $bar
　　Key Value
　　--- -----
　　a 1
　　b 2
　　c 3
　　Next assign a new value to the element "a" in $foo.
　　PS (6) > $foo.a = "Hi there"
　　PS (7) > $foo.a
　　Hi there
　　And let’s look at what happened to $bar:
　　PS (8) > $bar.a
　　Hi there
　　PS (9) > $bar
　　Key Value
　　--- -----
　　a Hi there
　　b 2
　　c 3
　　The change that was made to $foo has been reflected in $bar.
