Description
~~~~~~~~~~~

This function is an equivalent of `[x,...]=l(i)` syntax for field
extraction with the only difference that it also applies to `mlist`
objects.



Examples
~~~~~~~~


::

    l=`list`_(1,'qwerw',%s)
    [a,b]=getfield([3 2],l)
    
    a=`hypermat`_([2,2,2],`rand`_(1:2^3));// hypermatrices are coded using mlists
    a(1) // the a(1,1,1) entry
    getfield(1,a) // the mlist first field
