I'm not seeing a problem.

given: new T[exp]

If exp is not a compile time constant, return a dynamic-sized array of the 
runtime evaluated value.
else return a statically-sized array that can be implicitly converted to 
a dynamic-sized array.

The only problem I see is: how would this interact with CTFE?
