I know there is 'insteadof' but see my example, there is just one function implemented yet
still I get collision error. The traits are just usable very flat at the moment. If you have an
hirachical stucture of traits like I do, you have to do potentally exponetial count of
'insteadof's in the top level class even there's not one dublicate function
implemented.

Description:
------------
When extracting traits I would like to extract some general functions into sub traits and
'use' them in the traits where needed.
But when I compose a class out of multiple traits with sub traits I have to do obsolete statements
regardless if the colliding methods originate from same sub trait.
Just add a check if a method collides with itself
Test script:
---------------
trait A
{
public function a(){}
}
trait B
{
use A;
}
trait C
{
use A;
}
class D
{
use B, C;
}
Actual result:
--------------
Fatal error: Trait method a has not been applied, because there are collisions with other trait
methods on D in
