Could we kill call_user_func?

I'm sure this question has been discussed before, so if anyone can point to me to links or briefly recap I'd appreciate it. Why can't we make $someCallable() always work? E.g. http://3v4l.org/FLpAq I understand the problem of $obj->foo() where ->foo is a callable property. The workaround could be: ($obj->foo)(); call_user_func() just seems so ugly now that we have nicer syntax in so many other areas. Steve Clay -- http://www.mrclay.org/
