Re: Re: Release process

In my humble opinion 'null' is a 'pseudovalue' that has been made available for some time. If it was never intended for a script to be able to use it, it should never have been exposed. But it has been and many people, myself included, are using it. It is particularly useful to mark a value that has not yet been filled. The same way NULL is used in SQL. If you take out this behaviour there is no 'pseudo-value' to indicate the absence of value and we will go back to using 0 or constants, a hack at best. Also, I see a distinction semantically between isset and key_exists. Isset asks whether it is set to a tangible value. Key_exists asks whether the array contains an entry, any entry, for that key.
