Bug in System getOptions?

[Michael T. Richter]

I have this script whose contents comes straight from the web page:

-----8<-----
#!/usr/local/bin/io
options := System getOptions(args)
options foreach(k, v,
        if(v type == List type,
                v foreach(i, j, writeln("Got unnamed argument with value: " .. j))
                continue
        )
        writeln("Got option: " .. k .. " with value: " .. v)
)
-----8<-----

When I execute this script, here's what I get:

-----8<-----
michael@isolde:~/Io/IoSH$ ./test.io

Exception: argument 0 to method 'atPut' must be a Sequence, not a
'Object'

  Coroutine_0x821eb90
  -------------------
  atPut                               System.io line 42
  Object getOptions                   test.io line 2
  Coroutine setResult                 A3_Exception.io line 67
  Coroutine setResult                 A3_Exception.io line 67
  Coroutine main                      [unlabeled] line 0

michael@isolde:~/Io/IoSH$
-----8<-----

Even if I comment out the whole "foreach" statement I get the same
thing.  It really doesn't like getOptions.  However, if I do it
manually:
-----8<-----
michael@isolde:~/Io/IoSH$ io
Io 20060213
Io> options := System getOptions(args)

==>  Map_0x81fe790:

Io>
-----8<-----

As you can see it works.  I'm kind of stumped as to how to resolve this
issue (or, indeed, as to why it's happening).  Any ideas?

Hi Michael,

You'll need to track down the implementation of System getOptions. My guess
is it is somewhere in the vm/_ioCode directory. The bug in getOptions has
probably been introduced by other code changes. Possibly to do with ifNil
calls.

Indeed it has; this problem i thoroughly tested when I wrote that  
code. I will have a look at what the problem could possibly be tomorrow.

Thanks, Jeremy.  I took a peek, but am not yet fluent enough in The Io
Way <tm> to see what's going on.

I make no guarantees that I do things the "Io Way" as I'm sure folks  
like Quag can testify too after seeing some of my code. =]

I get the feeling I'm being made out to be an Io Way nazi.

Not my intention; didn't mean to imply that, sorry. Was merely  
referring that most of the Io code I write could use at least a few  
passes of refactoring before it looks like most other Io code.

Quag, be proud of the title.  Every language needs a "whip" to get
newbies into shape in "rightthink".  The alternative is a kitchen-sink
language like Ada, Perl, PL/I, et al.

Sorry. Now I'm the one being misunderstood. I don't have a problem being an
Io Way nazi. :)

Sorry it took so long to reply back, I completely forgot about this.  
Anyway, I've fixed the problem and made the change available in my  
darcs repo located at: http://repos.blurgle.ca:81/darcs/io and  
submitted it to steve for addition in his repo. So if you need this  
right away, feel free to fetch it from my repo using:

darcs pull http://repos.blurgle.ca:81/darcs/io

Note that the patch you want is number 3, you can safely ignore the  
first two.

[audrencezar]

To Try change:
-------------------------------------
options := System getOptions(args)
-------------------------------------
for:
-------------------------------------
options := System getOptions(System args)
-------------------------------------
It is ok for me.
