Are there languages that copy arrays in function calls
defaultly?
Perhaps Fortran has some convention that allows that but I doubt it
gets used very much, because it would be insane in most cases:
COMPUTE_MEAN_TEMPERATURE(ATMOS) is really *not* going to work very
well if it involves copying the ATMOS array.
I'm not completely sure about arrays, but at least Java has pass by
reference in some cases where you might expect pass by value. IIRC
function return values is a prime example.
