	Everything in classic FORTRAN is a passed as a reference -- even
constant arguments are passed as a reference to the memory location
containing that constant (which is why it was possible in very early
FORTRANs to have "a = 1 + 1" yield something other than "2" if preceded
by, say, "call mutate(1)" where mutate looks like: 

subroutine mutate(arg)
arg = arg * 2
end
