This is indeed a bug. Unfortunately, this case slipped and did not get tested. It
is a perfectly valid usecase, and should not require the use of insteadof at all.
Best regards

insteadOf in this case is just a workaround, since there is nothing to 'use
instead of' something else because here there is a property/method conflicting
with its very self!
And BTW insteadOf cannot be used as a workaround with properties.

This is still occurring with PHP 5.5, commit
cbe2870b72c4cfdb5c295e83c88d7cff5c39e396 (Fri May 3 12:25:49 2013 +0400).
Not being able to use multiple traits that have the same trait somewhere in their
composition trees is a rather major limitation of the trait system.

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.

public function bigTalk() {
echo 'A';

trait B {
public function smallTalk() {
echo 'b';
}
public function bigTalk() {
echo 'B';
}
}
class Talker {
use A, B {
B::smallTalk insteadof A;
A::bigTalk insteadof B;
}
}
