RE: Discussion: Closures

Hello,
What might also be nice is if we have something similar to Perl (I think
its Perl):

X = closure([cat, dog, fish]){
	Print($1);
	someMethod($2);
	$3 = $3 + 1;
};

Or

X = closure(3){ // 3 parameters
	Print($1);
	someMethod($2);
	$3 = $3 + 1;
};

Then

R = 3;
X.doClose(1, 4, R);
>> 1
>> you gave "4"
Print(R);
>> 4

And how is that different from java.lang.Runnable and run()? Oh, I see -
Callable.call() can return an Object, but run is a void run().

The only minor quibble I might have is for the parameter declaration
syntax.
Does this not look more natural?:

  x = callable() {
     foo = someMethod();
     bar++;
  };

  z = callable(foo, bar) {
     print(foo);
     someMethod(bar);
  };

  x.call();
  z.call(foo,bar);
