If a parameter is marked as ref then you have to assume it will be modified by the function (unless it's const/inout/immutable). If it's marked as out then you know it will be. If you didn't know that the function takes its parameters by ref or out... You're should've RTFM.
now imagine that you're reading some code:
foo(a);
vs:
foo(ref a);
which code style is easier to read without constant jumping into
documentation?
