Great work!
Thanks.
Output them to a Results object which, by default, sends the output to
document.write() but allows the user to redirect the output.  For
example, it might be nice to have test results pop up in a separate
window while the main page loads.
Hrm. I'll give that some thought. Not sure if it needs an object other 
than a function reference, though...

How about:
  if (some_condition) {
    // do your tests
  }
  else {
    skip(number_of_tests)
  }
That'd be easy enough.
And:
  while(todo(4)) { // sets an internal todo counter
    // each test automagically decrements the todo counter
    // ... but this should be transparent to the test code
  }
A little tricky, but do-able, I think.
Will this screw up a stack trace?
No, since right now there *is* no stack trace. I'm not sure how to get 
at that data in JavaScript.

Also, while javascript doesn't have
the Perl concept of context, are there any scoping issues this might
cause problems with?  Will passing a function reference have any chance
of altering the behavior of the code (it would in Perl).
I don't think so. Function references in JavaScript are purely lexical, 
so they always execute in the scope in which they are defined.
