You are missing the point, which is: `null' is being converted to the 
primitive string value ''.  A key of an *associative* array may be the empty 
string.  And that is good so.

What is questionable here is the implicit type conversion of non-numeric 
values to string.  But PHP is not alone there, so this behavior can be 
expected.  It might be nice if E_STRICT reported such spurious conversions 
or there was an even stricter mode that forbade them.  Perhaps in PHP 6 …
