Description:
------------
I had been assuming that the expression

$a = functioncall(), $a{operator}

is equivalent to

functioncall(){operator}

but this appears to be the untrue, at least in the case of functions returning array values.

Be kind to me. I'm sure I'm being stupid.

Reproduce code:
---------------
echo getdate()["year"];

Expected result:
----------------
2004

//(or whatever year it is)

Actual result:
--------------
parse error: unexpected "[", expecting "," or ";"
