This really isn't clear. Deciphering the intent of the code requires looking at
all the surrounding stuff, because it could mean something totally different in
an array. In other words,
// This would be a lambda
array_filter($source, $x => $x < 5);
// This would not
array($source, $x => $x < 5);
// and this would not
call_user_func_array('array_filter', array($source, $x => $x < 5));
The fact that the syntax for an expression isn't portable in places where (so
far) every other expression has been, is a serious concern.
Additionally, the proposed syntax is unusable for functions with more than one
line, making it similar in badness to if statements without braces. IMO the
current syntax for inline functions is perfectly sufficient, even for the PLINQ
example given earlier, and has massive advantages over this one in terms of
readability, affordance, flexibility, and language clarity.
