Re: Help with Matrix concept

[planhths]

mratsim: thanks! I was already using that one, but it requires proc signatures 
to look like: 
    
    
    proc op(a: AnyMatrix, b: AnyMatrix): Matrix

could concepts be usefull in this case so I can restrict to only i.e. `a: 
AnyMatrix[float] and b: AnyMatrix[float]`?
