They'll have to learn to deal with that.
It's a fairly general rule in computer programming: if something is not
mentioned in the documentation (or some more formal interface
description), you cannot make assumptions about it. [In practice of
course, you _have_ to make _some_ assumptions, but learning which you
can make and which you can't is an important part of learning to program
in a particular environment.]
