OK, well that part is easy enough if we punt to C:

   define method-string-to-double(s :: <string>) => (d :: <double-float);
      call-out("atof", double:, ptr: (as(<c-string>, s).raw-value));
   end;

Now, where to put it?

d2c/runtime.dylan/num.dylan ?
d2c/runtime.dylan/string.dylan ?
common/string-ext/conversions.dylan ?
common/common-dylan/common-extensions.dylan ?

somewhere else?
