I haven't used Julia yet, but from my quick reading
of the docs it looks like arguments to functions are

can change their arguments. My recollection from when
I first started using S (in the course of a job helping
profs and grad students do statistical programming, c. 1983)
is that not having to worry about in-place algorithms changing
your data gave S a big advantage over Fortran or C.

C also uses Call-by-Value.
C *only* uses Call-by-Value.
While literally true, the fact that you can't send an array by value,
and must send the value of a pointer to it, kind of supports Bill's
point: in C, you mostly end up sending arrays by reference.
