As Gerd said we are working on this., but I wanted to address some
other aspects:

There is no way to do this by design. Getting the logic of this
correct is difficult, and it it seems to be a bad idea to have the
.problem try and do this, since it reduces the reusability of the
homework problem, increases the amount of dependencies, and can cause
a backward compatability nightmare if we need to modify how things
work internally.

Only the functions listed in the help documentation are available to
problem. It should be impossible to access any other functions. If you
can that's a bug.
