As Steven's post shows, it would work if the left-hand side was immutable:

     immutable(wchar)[] wstr = "This is a wchar[]";

That line involves some help from the compiler: Because the type of the 
literal on the right-hand side is not specified, the compiler makes one 
that matches the type of the left-hand side.

In other words, one should not do what I did and assume that literals 
"like this" are always char arrays. They are char arrays only when there 
is c at the end "like this"c. Otherwise, although they default to char, 
the actual type is decided by the compiler.
