accumualte now supports multiple functinos - like min and max. As it now returns multiple results, the 'from' isn't appropriate. So we instead allow binding on the function directly. 'from' will still, for single functions it will behave as previously, for multiple functions I believe we throw an arror.


It would appear that you don't; the first function is returned via the pattern up-front.

JIRA forthcoming, since results can't be used on the RHS.

There's no way $c can be used in RHS code (5.3.0, current).
Is this the intended behaviour? Where can it be used?
