This gives this error message:
test.d(1): Error: 'auto' can only be used as part of 'auto ref' 
for template function parameters

Which is rather useless, and I have to dig into the code to find 
out why: the only way to instantiate a auto ref function is to 
call it. I think this is rather inconvenient.
