T const& versus T& const

[BasV]

Hi everyone,

I know

T const* a; // Pointer to T, object cannot be modified
T * const a; // Pointer to T, pointer cannot be modified. 

Now I was wondering if in the following example:

T const& a; // Object of type T, cannot be modified
T& const a; // ? 

The last one has any meaning? Does it? Or is it exactly the same as the first one?

I can't even get T& const a to compile.

References are immutable by definition, so applying const to them is redundant and illegal

Yes, makes sense. Thanks!
