Assuming you meant the statement in parenthesis... - Most prominent
one is the difference in parameter passing depending on the parameter
type; arrays are passed by reference, scalars by value. So any change
of array elements inside the function will change the array object on
the caller's side.

(There was also a case where awk got an issue in differentiating an
array from a scalar in functions, but details evade my memory at the
moment.)
