Strangeness in Phobos CI

[CarltonMcculloch]

Hi everybody,

I noticed something strange at Phobos CI.
std range package.d: Deprecation: storage class has no effect on 
type aliases.
What does this mean?
The error itself isn't too much of a problem, but it's annoying 
to have it in a template. I have no idea where it is trying to 
compile it or what parameters are used.
Can we make sure all template compilation errors print this stack 
trace? At a minimum, it should show the template parameters used 
to compile the code.
This goes a long way in making D errors easier to understand.
Can you help?
