2cc4429c62 When constructing code, use the `object-name' of the input port *only* 
if it's coming from a file -- not when it's a string.  In that case, use
`#f' for the name, so other code (specifically, `input->code') will use
'program.

536d0266df Use unsafe operations in `sort'. It has been running in safe mode for a 
while with no errors reported, and this change is done now when there's
time before the next release.

2368290cdb Test now that the generator is not in a running state when it's called. 
The previous problem was just a bug.

d5822a3ee5 Remove the special case hack for getting zero values at the end of a 
generator.  This will make this:

  (generator (yield 1) (yield))

also repeat #<void> when it's done which will be very confusing.  Better
just add a note in the docs on (generator (yield 1)) returning no values
when it's done.

Also, remove some of the `case-lambda' optimizations...

3a08648dab Added a `running' state, which is visible only from inside the 
generator.  (Also considered making it an error when the generator is
called while it is running, but that doesn't allow (yield (yield X))
fun.)

2f62cb192e Allow using `yield' with any number of arguments which will be returned 
as multiple values.  (These `case-lambda's are for making it fast, which
is probably stupid given how slow this is anyway.)

f1dcf49d38 Added `generator-state', implemented using a local state (which also 
simplifies the code that raises an error from the last change).

505034ea26 The generator function can now be used to send values to the generator. 
For example,

  (define g (generator (yield (yield (yield 1)))))
  (list (g) (g 2) (g 3) (g 4) (g) (g))

evaluates to '(1 2 3 4 4 4).  This is something that Python does (as a
generator.send method), which might be useful for using generators as
co-routines, and it is actually easy to implement since sending values
is exactly what we get when the generator call is actually calling the
saved continuation.  So most of the change is dealing with the
technicalities of throwing an error when the generator is called with
some arguments, when that's done after it's terminated (at the stage
where it's repeating the last value for ever).

A few tests added for this.

18c8e41fac Make it possible for the last expression in the body of a generator to 
return any number of values.  They will be collected and used as the
repeat-forever result of calling the generator again.

Note: there's an exception for using no values -- instead of returning
no values forever, use void, since no values can be more surprising, and
it can happen when someone uses something like

  (generator (yield 1) (yield 2) (yield 3))

since the result of `yield' is (values).  (This will change in a
following commit, but even then it will be popular since people will
usually invoke the generator with no arguments which leads to the zero
values.  Could be solved if you use (g (void)) -- but that's awkward, I
think.)
