better as a hyper-operator instead of a function (so that it works on

Hi,
I'm currently working on some Parrot bits, including some more cleanup of
the test suite.
For that it would be convenient to have commit right in CVS and rights in

/* [EMAIL
Often when I write a loop I want to run some code at loop entry time. It
would be nice to have a closure trait for this, similar to NEXT for loop
continuation or LAST for loop termination, but there isn't one. I don't
think either FIRST or ENTER do quite what I want. FIRST runs only once,

I've given here. For example, a junction can have a value like:
$x = ($a $b) ^ ($c $d)
which is true only if $a and $b are true or $c and $d are true but not
both.
That's why I allowed for virtual sets, defined by a closure.
