Re: NvP: s = s & 'x'

I see, has to be like this: 
    
    
    proc main() =
      var
        s: string
      
      proc `+`(a:string|char, b:string|char): string =
        a & b
      template fused2{a = `&`(a,b)}(a:var string,b:string|char) = a.add(b)
      template fused4{a = `+`(a,b)}(a:var string,b:string|char) = a.add(b)
      
      echo 'a' + 'b'
      echo 'a' + "b"
      echo "a" + 'b'
      echo "a" + "b"
      for _ in 0..50_000_000:
        s = s + 'x'
        s = s + "x"
      echo len(s)
    
    main()
    
    
    Run
