Subject: Re: [PHP-DEV] Introducing "Array Of" RFC
From: cryptocompress@googlemail.com (Crypto Compress)

Hello,

since there is an option for nullable type-hinted variables, it may be 
usefull to *explicitly* allow null values in a type-hinted array too.

e.g.: function foo(Bar[null] = null)

to consider:
- null is not an object
- null is not "nothing"
- null is not "not defined"
- null is not a/any type (even documentation states so)

Java: only reference types are nullable
c#: only if explicitly defined
sql: only if explicitly defined
