Comment (by JulianLeviston):

 I created the afore-linked issue in hint. I wanted to record my use-case
 here, too, which is that I'm building a meta-editing system (ie it can
 edit portions of its own code) and my codebase needs 3 to 4 levels of
 interpreting to have typechecked interpreted hotswappable zero downtime
 code modification.
