This compiles ...

 void main()
 {
  char[] A;
  char[] B;

  A = "abc";
  B = "def" ~ A ~ "ghi";
 }


But this does not ...

 void main()
 {
  dchar[] A;
  dchar[] B;

  A = "abc";
  B = "def" ~ A ~ "ghi";
 }

Errors are ...

test2.d(7): incompatible types for (("def") ~ (A)): 'char[]' and 'dchar[]'
test2.d(7): Can only concatenate arrays, not (char[] ~ dchar[])
test2.d(7): incompatible types for (("def" ~ A) ~ ("ghi")): 'int' and
char[]'
test2.d(7): Can only concatenate arrays, not (int ~ char[])
test2.d(7): cannot implicitly convert expression "def" ~ A ~ "ghi" of type
int to dchar[]

??? Why is this so ??? I can only assume that bare string literals are
presumed to be char[].

But this *does* compile ...

 void main()
 {
  dchar[] A;
  dchar[] B;

  A = "abc";
  B = "def";
  B ~= A;
  B ~= "ghi";
 }

So bare string literals are not always char[].
