But that is a big asterisk, which was my point. Only the compiled and running program is actually forced to working with physical memory. All stages before that is just modeling.

My belief is that we should stop conflating data types (input and state modeling) and program types (domain modeling) so we can advance to more productive workflows. F.ex runtime reflection should never have been a thing, instead the focus should have been on macros and staged compilation, most meta programming can probably be better evaluated design time rather than run time.
