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.
