Will this ever be possible ?


char [] str = 'A' ~ " string";

( im actually running through a string in a for loop , and it doesnt allow casting from char to char [] )

I think all primitives should at least have a toString property.

For the Moment you could use a canonical function

   alias char [] String;

   String CharRetString(char c)
   {
     String s="?";
     s[0]=c;
     return s;
   }

   String s= CharRetString('A') ~ "abc";

It seems like converting a basic type like char or int to a slice char[] or int[] would not only be possible, but cheap as well.  It's a one-dimensional, single element array!  ;)

That code looks bad. Remember we're not supposed to write over string literals; and why the String? Here's what I do:

char ch = 'A';
char[] s = (&ch)[0 .. 1] ~ "abc";

Have I ever mentioned that I think D needs a true const type modifier? ;)

char [] str = "hell";
str ~= 'o';

this works.

char[] str = "hell";
str = str ~ 'o';

this dont.

I ask walter for this, and i was answered that it is a bug, and it'll be fixed soon.
