To clarify: What this implements is that
$strlen1 = Closure::fromCallable('strlen');
$strlen2 = Closure::fromCallable('strlen');
var_dump($strlen1 == $strlen2);
// bool(true) with this patch, previously bool(false)
The same would also apply to the first-class callable syntax, i.e. after
this patch strlen(...) == strlen(...) would return true.
