E_NOTICE with trait method aliases

[kynx]

I'm getting Notice: Undefined offset: 1 in /path/to/vendor/zendframework/zend-code/src/Scanner/ClassScanner.php on line 596 using 3.1.0. It looks like this happens with aliased trait methods:

trait A 
{
 function a() {
 // does something
 }
}

class B 
{
 use A {
 a as b;
 }

 function a() {
 b();
 // do something more
 }
}

Stepping through the code it looks like $alias['original'] does not contain '::', causing the notice. I ran into this using zend-expressive-tooling on an existing project. It doesn't seem to cause anything other than annoyance, but I'm not sure if just adding a check for '::' would hide a deeper problem. Thoughts?
