The only problem I see is that when hovering a function name, it now prints the
whole function definition. When talking with @malaperle, he told me that you
had discussed it before and we should not have the definition in the hover,
just the prototype. Glancing quickly
simark added a comment.
Another example where pretty-printing the AST gives better results:
int x, y = 5, z = 6;
Hover the `z` will now show `int z = 6`, before it would have shown `int x, y =
5, z = 6`. I think new version is better because it only shows the variable we
care about.
