I'm afraid there aren't currently any hooks to support those operations.  But
any or all of those things would be easy to add.

The main interpreter loop reads "Line" constructs (ASTs) and executes them.
So you could do arbitrary stuff in that loop.

The namespace which holds variables and methods is pretty well documented.

I'd be happy to help if you want to get involved in adding these features.

Else we will get them done eventually, but I'm not sure when.
