your replacement tries to loop over an uint

Let's say your code is as your second example:

Hello.
Is there anyway in D to convenient fill a string variable with a char say X
times?
So, I'd like to do something like:
string divider( size, '-');// C++ notation.
$divider = '-' x $size;// perl notation.
I thought I could do the following:
const char divider[rowstr.length]

char[] divider = new char[5];

That assigns 0xff to all divider chars, and then assigns '-'. I think
there's a way to do it without the initial assignment.
In past there was some way to do that:
typedef char mchar = '-';

I wanted to create an simple wrapper around SDL. After my simple first

Well, creating a function for producing an array literal and returning it using

If you need to only print, you can:
import std.stdio;
import std.range;
void main() {
foreach (c; take(repeat('-'), 5))
write(c);

Oh, and if repeat had slicing (as it should)... '-'.repeat[0..5]
Still, it's far cry from Python's '-' * 5
