OK, so I was wrong, it is yet another type or variation of
the variable concept!
We need a state diagram for this...
And then another one for functions!
After that, if one already knows programming from somewhere
else, it would be enough to just look at these two diagrams.
Because what else is there to programming other than
functions and variables?
Oh, maybe a big note: "Don't do it, son."
