Item

An "item" works like a variable, you can assign it a new value.

                     To Item                      ?                   
s = "○◍○○" s[2] = '●' "○●○○"
s = "○◍○○" s[2] = "●●" {'○', "●●", '○','○'}

Fill

Atom to slice, all items get the same value.

                     Atom Fill                    ?                   
s = "○◍○○" s[2..2] = '●' "○●○○"
s = "○◍◍◍" s[2..4] = '●' "○●●●"

New Items

A "gap" starts with nothing, you can not assign an atom to a gap, but you can assign any sequence to a gap.

                     To Any Gap                   ?                   
s = "○◍○" s[2..1] = '●' "○◍○"
s = "○◍○" s[2..1] = { '●' } "○●◍○"
s = "○◍○" s[2..1] = "●" "○●◍○"
s = "○◍○" s[2..1] = "●●" "○●●◍○"
                     To Head Gap                  ?                   
s = "◍○○○" s[1..0] = '●' "◍○○○"
s = "◍○○○" s[1..0] = "●" "●◍○○○"
s = "◍○○○" s[1..0] = "●●" "●●◍○○○"
                     To Tail Gap                  ?                   
s = "○○○◍" s[$+1..$] = '●' "○○○◍"
s = "○○○◍" s[$+1 .. $] = "●" "○○○◍●"
s = "○○○◍" s[$+1 .. $] = "●●" "○○○◍●●"
