Somehow along the line from BCPL to B to C, one useful feature was
lost: the ability to have a value-returning statement block inside an

if so thats probably sad, though i dont know how it looked like

as to this loop as i said i had no ide how to make indexes like i
in this form but what comes to my mind now is maybe something lika

those i,x,y  in loop 'headers' could be possibly subscripted

overally not bad, i could somewhat accept that loop
(yu wouldnt belive how hard is come to that syntax conclusions,
literally takes years, and not 5 years more like 15)

i wanted to compore how many chars my thin c skin conventions would
make (but not having funic F for wloat or runic U for unsigned) i put `
and the spare is not great becouse c is quite thin - hovever it uses a
lot of what i call 'decorators i eman not necessary ().; which could
be changed to spaces, it not spares chars but somewhat spares ink
on fictional snippet (probebly not working)
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(int i=0;i<(int)m;i++)set_pixel(x+=dx,y+=dy,color);
}
thin skin
draw_line`x`y`x2`y2`color
{
     `wx=dist x x2,`wy=dist y y2,`M=(wx<wy?wx!wy)
     `dx=wx/m,`dy=wy/m, M'set_pixel x+=dx y+=dy color;
}
