Not exactly. A string literal implictly casts to all 3 string types. You can
add
a suffix to force it to be a wstring or dstring (I don't think that there's a
suffix
for a normal string though), or you can cast it to the exact one you want, or
you can assign it to a variable first. If you use auto, I believe that it will
default to string rather than wstring or dstring, but string literals
implicitly
cast to all 3, so the compiler considers your code to be ambiguous.
