I chose the term aggregate, because it is the term used in the 
description of the foreach syntax.

foreach( value, key ; aggregate )

aggregate being an array or range, it seems to fit as even when 
the aggregate is an array, as you still implicitly have a range 
being "0 .. array.length", and will have a key or index position 
created by the foreach in addition to the value.

A wrapped function could very easily be similar to the intended 
initial outcome

void example( ref float a[], float b[], float c[] ) {

    foreach( v, k ; a ) {
       a[k] = b[k] + c[k];
    }
}

is functionally the same as

void example( aggregate ref float a[] ; k, float b[], float c[] ) 
{
    a[k] = b[k] + c[k];
}

maybe : would make more sense then ; but I am not sure as to the 
best way to represent that index value.
