Slot is a struct, and slots is Slots*[].  But anyway, I found the
problem.  I needed to explicitly declare slot as:

	inout(Slot)* slot = ...

because for whatever reason, auto turns it into inout(Slot*) which
cannot be modified.

I think inout is one of those things that really needs more thorough
treatment for newbies, because coming from a C/C++ background I had no
idea what was wrong. Now that I get it, it makes so much more sense.
