When using EntryPoint attribute in fsx script top-level code is not executed

[0101]

Let bindings still work, but side-effects are not executed.

Repro steps

script.fsx :

printfn "Hello world"

[<EntryPoint>]
let main _ = 0

dotnet fsi script.fsx

Expected behavior

We see Hello world printed, as it is when there is no [<EntryPoint>] used (sharplab - no EntryPoint).

Actual behavior

Nothing is printed. (sharplab - with EntryPoint)

Known workarounds

Don't use [<EntryPoint>] in scripts - as it's not executed anyway, see #1431

Considerations

Using [<EntryPoint>] in a script could just raise an error which would resolve this issue. It would cause a breaking change though for scripts that are imported from other scripts, because this currently works as expected:

script1.fsx:

let hello = printfn "Hello %s"

[<EntryPoint>]
let main _ = 0

script2.fsx:

#load "script1.fsx"
open Script1

hello "world"

dotnet fsi script2.fsx prints "Hello world"
