That is funny & interesting. If you're only using text keys you can do this:
<?php
function sillyFunc() {
return array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e'=>'some string');
}
function objectize($val) {
return (object)$val;
}
var_dump( objectize(sillyFunc())->a );
var_dump( objectize(sillyFunc())->e );
--- output ---
int 1
string 'some string' (length=11)
