Here you're assigning the return value of the function x() to the
variable $a.

> $a[0] = 42;

Here you're writing to the variable $a (or rather, in this case, to an
element of the array that is variable $a).

Neither of these is trying to assign (write) a value to the return value
of the function call. Whether you call the issue syntactical or not is
just irrelevant and messing about with semantics.
