http://bugs.php.net/bug.php?id=43577 was closed
as "Won't fix" with
only  
the message "We discussed this already as well a few times, also not 
going to happen." 

I can't commit there since the bug is closed, but what is the reasoning

behind not allowing this bug to be fixed? (The bug didn't link to the 
discussion, and I wasn't able to find it.) Does "Won't fix" mean 

a) the developers have no plans to fix this themselves, but will 
consider patches that fix it?

b) or, this change is not desired, and any third-party fixes will be 
rejected?

Johannes, can you mark this bug as a duplicate of the known feature 
request, or provide a link to it? Thanks.

This request was made multiple times before, currently there's no
developer having a good fix for that, setting to bogus since it's a
known request.

Description:
------------
It would be nice if PHP could allow you to use the [] operator to index

within an expression that evaluates to an array, as if it was a 
variable.

This feature request is similar to #41268 "Access array member without

variable", but suggests using the existing [] operator rather than 
adding a new function. I could not find further details on
php-internals 
about this issue.

Reproduce code:
---------------
For example:

  $lines = split("\n", $text)
  print $lines[0]

cannot currently be written as

   print split("\n", $text)[0]

nor

   print (split("\n", $text))[0]

Expected result:
----------------
The second and third examples behave identically to the first.

Actual result:
--------------
Parse error: syntax error, unexpected '[' in - on line 2
