New Comment:
PHP is a dynamically typed language. It can't in the general case know what
type is expected. Simple example if f1() + f2(). Here int, float and array
would be viable return types.
Whether the return value is used or not is known to the engine and also exposed
to internal functions.
But I don't think that it makes sense to expose it to userland functions.
Functions shouldn't behave different based on whether the return value is used
or not.

Description:
------------
I would like to be able to tell if a function was called from a context that is
expecting a return value or not. Additionally what type is expected.
eg('hello'); // called not expecting a return value
echo eg('hello').' world'; // called expecting a string
function eg($s)
{
if(return){ // suggested overloading of the return keyword to report the
function context.
return ($s);
}
else{
echo $s;
}
}
Additionally
gettype(return);
and
is_string(return);
is_array(return);
etc
