Comment (by JulianLeviston):
Oh that's much clearer, thank you. I'll have to dig in more to find out
about the split of compilation of loaded modules versus expressions (at
GHCi prompt and/or given to `-e` flag) to think about how to separate
those two types of code.
As far as I can see so far in my explorations, `HscInterpreted` (ie the
target) is the marker used to determine whether to compile to bytecode or
not. Loading with `-e` or `--interpreted` sets this, and Setting
`-fbytecode` sets it, too, and conversely, setting `-fobjectcode` sets it
to the standard compile target for the platform (which is near
`HscInterpreted`.
Thanks for being so helpful and patient.
