The function module_invoke_all needs to be updated as well.
Won't this break arguments passed by reference? Did you test such

Try this: module_invoke('taxonomy', 'get_tree', 1); and compare the
results with taxonomy_get_tree(1); 
What happens is that taxonomy_get_tree is called by the arguments 1,
NULL, NULL, NULL which breaks it.
Hence the patch.
Every Drupal version I have met (4.4, 4.5, CVS) contains this error. I
think this led module authors to not use module_invoke (at least I did
so until now) which will be quite a problem if we decide on breaking up
the modules into smaller pieces.

I have no idea how else we should fix this. +1.

Of course, lambda is another solution. When I objected on IRC that
call_user_func_array is slower, Bart Jansens pointed out that
slashdotted pages are cached thus module_invoke is not called. So if
this solution is accepted, the credit goes to him.
But one of the solutions shall be accepted.

The message was wrong (but funny).
