Was wondering if this feature could be implemented, right now auto needs
to be written like this:
    auto pValue = someFunctionReturnsRef(); // forgot '&', still valid

didn't want one

The feature would make the code look like this:

    auto* pValue = someFunctionReturnsRef(); // error expecting pointer

We don't accidentally make a copy when we wanted a pointer. C++ has a
similar semantic for it's auto.

Hm... I'm not familiar with C++ auto, but C++ does have local 
references. D does not.

I'm not sure if you are asking for the syntax specified, or asking for 
the original line to be treated like the specified syntax. The latter 
absolutely is not going to happen, because that breaks valid code.

Even if we added:

auto* pValue = expr;

I don't see why this is more advantageous than:

auto pValue = &expr;
