I typed the command `se` but an error is thrown. Is it because `se` is no longer supported? If so, which ASTInterpreter commands are not available in ASTInterpreter2? Thanks.

```julia
1|debug > se

Thanks for trying it out. Just an oversight. I’ll look into it.

`Up` key doesn’t recall previous commands in `1|julia` mode, though it works for `1|debug`. Is this deliberate? Can’t remember if it is so in `ASTInterpreter`. Is there a way to enable recalling under `1|julia`?
