It depends on your point of view imho.

You can describe a function call from 'outside', ie I give it values for its
parameters, and it returns me a computed return value.
You can describe the same thing from 'inside', ie I get values from my caller,
compute a result, and output the result.

I would consider this yet another view, namely performance. Function calls are
stil happening, but you focus more on the #calls/second, ie throughput.


So depending on what one is interested in, I think, one structures and
describes what is happening in a different way.
Wouldn't that be a possible explanation for all the subtle different ways of
describing the same thing?
