Is there a way to convert GIMP steps to manipulate an image to GEGL function calls?

Question

I have a set of steps in GIMP that I want to automate in Python. How can I translate what a GIMP tool does to GEGL functions?

This started with me trying to write python scripts that call some GIMP steps (since I want the source code to live in a lambda function) However, I soon found out GIMP runs the python scripts not the other way around.

After more digging and reading I found a post that pointed me to GEGL. After confirming there existed python bindings for GEGL I decided to search for information about their API and how GIMP uses GEGL. Found nothing so far.

The list of steps are more or less:

1. Curve bends
2. Gaussian blur
3. Linear burn
4. Change saturation
5. Merging layers
6. Transforms

The GEGL source is here

There are two Python examples, here and there
