Conceptually, an array indexing operation *is* a function call. This is
especially clear when the array elements do not directly map to memory
locations, because then you need to implement an algorithm to find the
nth element of an array.

And even if they directly map there is a function call, even if it as
simple as 'increment the address pointer by the difference of the index
and the base address'.
