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.
