If you need to only print, you can:

import std.stdio;
import std.range;

void main() {
     foreach (c; take(repeat('-'), 5))
         write(c);
}

I know, I know, you said *convenient* ;) I heard write(ln) is to print  
arbitrary ranges, so this'd come down to:

writeln(take(repeat('-'), 5));

and if universal call syntax worked correctly then even this would be  
possible:

writeln('-'.repeat.take(5));

much easier to type.

BTW, I stumbled on this when crafting the example:
