Well, GHCi has no main, so it doesn't seem surprising (to me) that it's

If we start GHCi then run the function called 'main', we should ideally get
the same behavior as building with GHC then executing the process.
Variations make exploratory programming with GHCi very difficult, especially
with concurrent haskell.

That sounds good, too. I think it worth looking up what the drawbacks will
be. It might be an acceptable trade even if there are minor drawbacks. I
would imagine the main benefit of the sandbox is ability to interrupt a task
- i.e. job control from the GHCi shell.
