I am not sure I get you here, when I call ruby -a it surely would not
be too late for the compiler to keep the AST. My question was rather,
would it be too much overhead for the VMs to be prepared to have the
AST and expose it via an API in that case?

Probably that is much work OTOH it would be great for studies and experiments.
I hoped Charles would have some time to give me his view on this, but
of course he is a very busy man.
