We actually do need it to be initially untyped.  If every string literal was
implicitly utf-8, the following functions could not be called with a literal:
void fun(wstring s);
void fun(dstring s);
void fun(const(char)* s);

What is important is that a default type can be automatically used, and it
already works this way some of the time.
auto x = "blah blah"; // x is typed as string

Extending this default type to function calls seems natural to me.
