Sorry for the type, it should read "mixing".
Once again. Interfaces are declared stuff - __call is not.
Since PHP does not have templates and will never have them that is the
end of the story.
Well you could experiment with pecl/runkit' runkit_method_add().

Isn't __call a reasonable way to implement methods? Sorry to re-open
this one, but I am not convinced of the opposite yet. But I am open for
an explanation.

Thank you for the quick reply and the proposed generic function body.
What do you mean by "You would be missing two completely different
things, descriptive and non descriptive semantic elements."?
I could use
function <name>(<signature>) {
$args = func_get_args(); return $this->__call(__FUNCTION__, $args);
}
(which fixes 2 bugs in your suggestion) but I would prefer an
abstraction over copy&paste.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
You would be missing two completely different things, descriptive and
non descriptive semantic elements.
What you can do is providing the implementation of the interface
methods all with the same body:
function <name>(<signature>) {
return $this->__call(array($this, __FUNCTION__), func_get_args());
}
where <name> and <signature> have to be replaced with the method name
in question and its parameters respectively.

Description:
------------
When implementing an interface one cannot use __call to implement
methods as this will lead to a FATAL ERROR. However it would be quite
convenient if one could do this. It would e.g. allow to generically pass
on method calls to an object that is stored in a local variable and
implements the interface.
Reproduce code:
---------------
interface MyInterface{
public function myMethod();
}
class MyImplementation implements MyInterface{
public function __call( $method, $parameters ){
// do something
}
}
Expected result:
----------------
__call takes care of not explicitly implemented methods declared in
MyInterface.
Actual result:
--------------
Fatal error: Class MyImplementation contains 1 abstract method and
must therefore be declared abstract or implement the remaining methods
(MyInterface::myMethod)
