though eventualy it canm be written shorter i guess
   draw_line`x`y`x2`y2`color:
  `m = min 'wx=abs x2-x 'wy=abs y2-y) ' set_pixel x+=wx/m y+=wy/m color;
  ;
 not to say it lookin specially good but welll..

There are ways to have more compact syntax without it turning weird, leaving out types, and using backtick separators and other strange punctuation (or is that lone ')' a typo?).
Start with this version:
   void draw_line( float x, float y, float x2, float y2, unsigned color)
   {
       float
        wx=dist(x,x2),wy=dist(y,y2); int m=wx<wy?wx:wy;
        float dx=wx/m,dy=wy/m;for(inti=0;i<(int)m;i++)set_pixel(x+=dx,y+=dy,color);
  }
For example:
    void draw_line(f32 x, y, x2, y2; u32 colour) {
        f32 wx = dist(x, y2), wy = dist(y, y2)
        int m = min(wx, wy)
        repeat m {
            set_pixel(x += wx/m, y += wy/m, colour)
        }
    }
Summary:
- Allow shared types in parameter lists
- Auto semicolon insertion
- Built-in 'min/max' operators
- New repeat-n-times loop
- Shorter type names
