Indirect call and pass of function (Closure implementation based on function pointer)

Function pointer:

/pointer function get <function name> <target> <targetObjective>
/pointer function call <target> <targetObjective>

example：

/scoreboard objectives add funcPointer pointer
/scoreboard objectives add closure pointer
/summon pig ~ ~ ~ {tags:["A"]}
/summon pig ~ ~ ~ {tags:["B"]}
/pointer function get custom:example/test @e[tag=A] funcPointer
/scoreboard players operation @e[tag=B] closure = @e[tag=A] funcPointer
/pointer function call @e[tag=B] closure #the same as /pointer function call @e[tag=A] funcPointer and /function custom:example/test.

Entity pointer:

/pointer entity get <entity> <target> <targetObjective>
@e[pointer={<target>=<targetObjective>}]

example：

/scoreboard objectives add entityPointer pointer
/summon pig ~ ~ ~ {tags:["A"]}
/summon pig ~ ~ ~ {tags:["OBJ"]}
/pointer entity get @e[tag=OBJ,limit=1] @e[tag=A] entityPointer
/kill @e[pointer={@e[tag=A]=entityPointer}] #the same as /kill @e[tag=OBJ] .

Pointers give commands more flexibility.

I can't seem to figure out what exactly this would do; could you perhaps explain as well and not only list examples?
