This will raise the same issue as we have/had with the reflection API:
mike@honeybadger:~/build/php-unicode-debug$ cli -r 'interface i{function f();} class c implements i{function f($a){}}'

Fatal error: Declaration of c::f() must be compatible with that of i::f() in Command line code on line 1


Nah, don't look at me--I don't like that either.

Huh? Rename or alias? It can't implement Iterator if there's no rewind() method.
