There's several things in the jextract generated code which result in accidental complexity, and make it hard for developers to find what they are looking for.

* methods like $LAYOUT() - use of dollar and upper cases are distracting here
* upcall interfaces have a lot of visible public fields (descriptors/method handles), which is a bit confusing
* For global variables, we generate getters/setters, but also a $LAYOUT and $SEGMENT accessors, which can be confusing
