Guides that are created like Bezier curve or a straight line

One could create a guideline that can be a different angle than perpendicular or slanted, as well as making curves aswell. Node handles, nodes, lines, and endpoints could snap to the position of the dyna-guide when they are moved close to the dyna-guide (the distance could be user definable (like current guides)). This can be accomplished by making objects snap to the position of closest point of the dyna-guide. The position's coordinate ( (x,y) graph style) can be found by using the mathematical equation of the dyna-guide's principal bezier curve/line.

So, instead of a guide that is Horizontal, and having objects snap to it by constraining their y cordinates to be only that of the guide, the dyna-guides will constrain the object's position to the actual x AND y cordinates of the principal bezier curve or angled line. It would be sweet to see dyna-guides that that are rays also, so that their one point stays the same, but the angle of it rotates around the one point. All these features would make dyna-guides super useful, especially when creating vector images with a perspective. I apologize for the complexity of the description, and my inability to program this feature. If someone else could program it and implement it into the next inkscape, i would be very thankful.
