It’s pretty hard to judge which subtree to move over at a given point in an AST. For example, when point is at | in the following text:
(|X.y(z), alpha)
Should point move over X, or X.y, or X.y(z)? All three subtrees has their beg=(point). A human can tell (and might disagree on) which unit to move across, but a program couldn’t tell. Without language specific knowledge, it can’t really decide.
Just a thought, but maybe we can let major modes define what’s an “abstract list”, and sexp-forward would move across the immediate children of abstract lists. Eg, abstract lists in C would contain block, argument list, statement, etc. And in the example above forward-sexp would move across X.y(z) because it’s an immediate children of the enclosing abstract list, the argument list.
