Indeed. This is the same answer I was going to give.
Run-time code generation implies a whole bunch of different scenarios with
a whole bunch of use-cases. There are resource sharing concerns, security
concerns, and performance concerns that need to be nailed down. Otherwise
it is difficult to identify whether it is possible or desirable to
accomplish what the original post is inquiring about.
