Okay, I never used Perl.

As long as people don't have to use isset anymore to check for a not-null, 
perhaps over time this widespreadedness would become less.

As soon as you can use "unless (is_null())" to check whether a variable 
exists and is not null, the need for using isset for this should greatly 
diminish...

Just my perspective. I don't know what other people think, the boogieman 
of this list seems to not want to discuss anything related to this, so I 
don't know.

I mean for me it means having to rethink my thinking, i.e. to get used to 
this new statement. But it would probably become very natural?

I would imagine a lot of people becoming enthusiastic about an "unless" 
statement. It is also a sexy thing to introduce and it doesn't require any 
changes to existing code.

Again, just my perspective. Curious what other people really think at this 
point.
