Hasta La Motion!

I was wondering if anyone knows if Nuke can understand keyframe animation through expressions like Shake is able to.

This is an example of what I mean in Shake:

A mix node’s expression with a keyframe at frame 1 with a value of 0 and a keyframe at frame 2 with a value of 100 looks like this:

Hermite(0,[0,99.36,99.36]@1,[100,99.36,99.36]@2)

I want to be able to do something similar with Nuke but when you create keyframes in Nuke it just references a "curve". There must be a way to get the data from the curve since it is all based on math.

Any ideas?
