Question about auto ref

[Namespace]

So I changed it into 'ref&'.

Quick example:

[code]
void bar1(ref& A a) { } // OK
void bar2(ref &A a) { } // OK
void bar21(&A a) { } // Error: '&' can only be used in 
combination with 'ref'.
void bar22(& A a) { } // Error: '&' can only be used in 
combination with 'ref'.
void bar3(ref const& A a) { } // OK
void bar4(ref const &A a) { } // OK
void bar5(ref &const A a) { } // Error: '&' Must be directly used 
in front of the type.
void bar6(ref& const A a) { } // Error: '&' Must be directly used 
in front of the type.
[/code]

Thoughts?
