What is type slot, and how is it constructed? This snippit isn't
enough to provide help.

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 was wondering, because your error message identified it as inout(Slot)*,
which should be modifiable...
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.
It's kind of a new concept to D even (since 2.056). It's not completely
fleshed out yet, Timon, Kenji, and Stuart have some great ideas on making
it better.

I plan to write a const/inout article at some point.
