I don't understand that inconsistency.

   public Foo function bar() { }

looks perfectly sane to me. PHP's syntax was very heavily influenced by
C from day 1. In C you have:

   static int bar() { }

In PHP the 'function' keyword indicates what follows is a function.
Putting something in between the function keyword and the name of the
function would confuse me. To me "function bar()" is inseparable and is
equivalent to "bar()" in C which makes the above examples consistent
with each other.
