LOL. Obviously using the variable $noop works but I was hoping that the feature would 1) allow looping through keys w/out needing a variable for unused values and 2) possibly a speed bump over using array_keys.

How about using '$noop' ?

In which case, the feature is complete.

Description:
------------
Too often I do something like:

foreach( $array as $key => $noop )
{
  // do something with $key only
}

Why not use array_keys? Well, I guess to avoid the overhead of calling a function. It would be super if we could simply do:

foreach( $array as $key => null )
{
  // do something with $key only
}

I am not 100% set on using null, but I will let the community decide on the specifics.
