Hmm...never knew about that one.  It seems poorly named.

The array_map() changes would allow for multiple arrays of values:

array_map($keys, $vals, $vals2, $vals3);

Which I suppose could be emulated with a combination of array_combine() 
with array_map():

array_combine($keys, array_map(null, $vals, $vals2, $vals3));

But it would execute faster if it were supported in array_map().  If it 
is supported in array_map(), then array_combine() could call array_map() 
and could potentially just be an alias to array_map().
