Inconsistent analysis for top-level module in F# script

[DedSec256]

In the script files, the following code is analysed in the editor without any errors

module A

let x = 3

but if you send this code to the FSI in any way (IDE, dotnet fsi file.fsx, dotnet fsi --use:file.fsx) FS0010: Unexpected start of structured construct in definition. Expected '=' or other token. error will occur

Either top-level modules must be allowed in execution with fsi, or the corresponding error must be shown when analyzed in the editor.

• .NET 8
• Rider 2024.1 RC 1, VS Code, dotnet fsi

Namespace declaration groups and module definitions are not allowed in script fragments. The FSharp spec (Page 298) says script-fragment : module-elems And module-elems is what you find inside a module. Having said that, I have come across this issues multiple times when moving from script to project and back. But from the little that I know about the internals of fsi, I think it won't be easy to allow modules.
