 Note, that students are not permitted to use any variable name defined by the teacher in the question variables.  This includes both the context variables, and the regular remaining question variables.  It is not possible to define variables which a student can then use.  Students _can_ use function names defined in the preamble. e.g. you can put `vec(ex):=stackvector(ex);` into the preamble.
