proc in array, ...but is it the solution?

[ingo]

The more complex ones have 6 variables per proc and need some pre processing to 
get those variables. One has a proc for the divisor. But, looking at it all I 
could just as well create a proc for initialisation of the curve (pre)process 
all the procs needed to get the matrix values and returns an object:
    
    
    Curve = object
        #curve_type: string
        dim_seg: int
        step: int
        end_at: int
        divisor: float
        matrix: seq[seq[float]]
        pointarray: seq[seq[vec]]
    
    proc init_simple3ESC(pointarray, esc):Curve=
      var curve = Curve()
         curve.dim_seg = 1
         curve.... etc
      process procs here to obtain matrix data
       ...
      return curve
    
    c = init_simple3ESC(pointarray, 2)
    
    p = getPoint(c, 0.8)
    
    
    Run

A bit more typing but nicely explicit.

Thanks, I'll look into the macro solution.
