What is to!c_str() supposed to return?

To be a useful alternative to toStringz() it needs to be

  char* to!c_str(string s) (or immutable(char)* or something)
i.e. the related toImpl looks like
  char* toImpl(c_str, string)(string s)
=> 3 types! (char*, c_str, string)

But the signature of toImpl is
  T toImpl(T, S)(S s)
so the related to's signature is
  T to(T)(S s)
or something like that.

This means, that the return type T is the same type you instantiate to
with.
That means to!c_str(string s) will return a c_str struct and not a char*
And, as I explained in my previous post, C functions want a char* not a
struct c_str.
