( iteration control stacks
We create two new stacks - a small stack to hold the "current" value
of the loop, or the "i" stack, and a larger stack to hold any extra
state, as well as the cp of a word that moves to the next value, which
we call the "next" stack.
state, which we call the "next" stack. Typically the top of the next
stack would contain an "iterator" that knows how to advance to the next
value and how to be cancelled, depending on the needs of the calling code.
With these two new stacks, we can create a generic loop construct for
iterating over streaming values. Not only that, but those values can be
arbitrarily filtered and transformed simply by pushing a new value onto

"nextcount" must be the number of items that are being taken up on the next
stack by this word. For simple iterators this will be 1, for the space
the iterator word takes. If "more" is 0, this number of items will be
dropped. This is always returned even if there are more items to iterate
over, in order to support efficient cancellation. ">cancel" will push a word
onto the next-stack that will query the iterator below it to determine how
many items need to be dropped. It will drop one item from the i-stack if the
iterator indicates that there are more items.

If an iterator requires any more complex cleanup to happen as the result
of a cancellation, such as dropping multiple items off the i-stack, or
aborting a task, it should check the "cancelled" flag to determine whether
to perform it. An iterator that returns 0 0 will not cause any further
changes to occur to the iteration stacks, which allows it to be in complete
control of this scenario if needed.
( iterators are pointers to an array containing two function pointers:
xt-iter xt-cancel
The xt-iter word must take care of updating the stacks directly. If
there are no more values, it must remove the values from the i-stack,
drop itself from the next-stack, and return 0. "finished" and "finish?"
are useful words to help with this.
The xt-cancel word should remove all of the iterator's state from the
iteration stacks and return nothing. "n-nextdrop" and "iterdrop" are useful
words to help with this. If the iterator is itself making use of an
iterator below it on the stack, the xt-cancel word should call "cancel" to
recursively clean that up once it's done.
Note that all "next" words _must_ be defined in the target Forth!
This means that any iterator that dereferences near memory, such as "links",
WILL NOT WORK on the host Forth! )
( get-next returns the result of the iterator in swapped order - it is usually
more convenient to specify the count last when writing iterators, but it's
always more convenient to check the flag first when consuming the result. )

( yielding from a generator has three moving parts:
suspend: run immediately when the generator yields. takes care of updating
the i-stack appropriately, as well as potentially saving any
yield-specific state to the next-stack. After this runs, the
generator's extra parameters are pushed to the next-stack, along
with the generator's "resume" pointer and the yielder's iterator.
resume: run when the generator is resumed by iterating. Before this runs,
the yielder will take care of placing the "resume" pointer back
on the stack and restoring the generator's arguments, so the
stack environments should match what they were when the suspension
happened. This deals with cleaning up after the yielder so the
rest of the generator can run.
cancel: run when the generator is aborted. Before this runs, the next-stack
is cleared of the "resume" pointer and all of the generator's
arguments. This should remove any yield-specific data from the
iteration stacks, and potentially call "cancel" to clean up the
iterator underneath if the yielder is intended to map or filter
another iterator. )

Waddles, your trusty pig, is ready to go on the hunt for truffles! Leash him
up and make your way through the grove. But be warned! Digging too close can
cause damage to the truffles' mycelia, which can take years to recover from!
HOW TO PLAY:
Select a square with the arrow keys, and press the space bar or enter to dig.
Waddles will tell you how many truffles are nearby by marking the square with
a number. This is the number of neighbouring squares (including diagonals)
that have truffles.
