I have some string generate from template, and I need to dump them to
stack and modify it. So I write:

template S(int n) {
  const char[] S = "n = " ~ n;
}
void f() {
  char[S!(123).length] s = [S!(0).tupleof];
  s[0] = 'm';
}

The problem is, there is not a 'tupleof' property on array. Should this
feature be buildin ?

I forget the n.stringof, it should be:

template S(int n) {
  const char[] S = "n = " ~ n.stringof;
}
void f() {
  char[S!(123).length] s = [S!(0).tupleof];
  s[0] = 'm';
}

no. What would it return? contents of the array? What would it do with a 
non const?

I think you can get the effect you want with a cast ot a slice or maybe both.


also somthing along this line should work.

template S(int n) {
const char[4+n.stringof.length] S = "n = " ~ n.stringof;
}

What's wrong with simply

void f() {
    char[S!(123).length] s = S!(0);
    s[0] = 'm';
}
