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;
}
