The type of "test" is string, isn't it?
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.
I think it's a bug. This compiles:
void check(int i) {}
void check(long i) {}
void check(short i) {}
void main()
{
check(1);
}
