D - string inconsistencies?

It seems to me that that are some inconsistencies in how strings are handled. For example, const char a = "a"; // okay char b = "a"; // runtime error These should be handled the same. Also, this causes some issues in calls to C API calls. Suppose that there is a function: void foo( char *p, int *len ); which fills in p with values and sets len to the length. You can call the function like: char[maxsize] myp; int mylen; foo( myp, &mylen ); but now, the length of myp is set to maxsize, and the comparison operators don't work. If the value placed into myp was "xxx", then char myvalue = "xxx"; if (myvalue == myp || icmp( myvalue, myp )) is always false because it appears that the lengths don't match. If you say printf( "%.*s\n", myp ); it knows the length of myp. It makes sense that the cmp() and icmp() routines would also, and do the comparison based on that.
