Re: [rules-dev] accumulate to acc

We are looking to tighten up accumulate, using a new keyword to
differentiate. It will use ; for separation, to follow a similar form to
a 'for' loop.
acc( CE*;
<func>*;
<guard>? )
so something like:
acc( $o : Order();
$min : min( $o.value ),
$max : max($o.value);
$min > 100 && $max < 100 )
Given that I can do this today using an eval after the accumulate CE: What's
the big gain, as compared to the nuisance of yet another CE, with the need
to document (which, traditionally, isn't done so eagerly) and teach and
learn and getting it free of bugs?

I have wondered if we could use pipes on our functions, to be able to
pass the results of one function into another - just not sure how that
will work or look yet.
func(...) in func(...)
func(...) | func(...)
