Bug description:reset() & end() to return value for "not variables" like empty() in
PHP 5.5

Description:
------------
Since PHP 5.5 empty() supports arbitrary expressions, could PHP do same
with reset() and end()?

I can simply add [0] to end of variable or function to get value of last
element. However this approach does not work when I use arbitrary or
non-integer keys. It is even more tricky when I want "just get last
value" of array.

Expected result:
----------------
I would welcome to be able to get first and last value of "any kind of
array" like this:

reset(someFunction()); # returns value of first element

end(explode('/', '/very/long/path/to/filename.txt')); # returns filename
without path (value of last element of explode())

Actual result:
--------------
end([]); # Fatal error: Only variables can be passed by reference
