Can't #load recursive namespaces into FSI

[mciccottidmg]

A file with a recursive namespace reference can't be loaded in FSI. This is similar to #237.

It does compile as part of a project.

Steps to reproduce:

1. Create a file named "test.fs" containing:

namespace rec FakeNamespaceName

module AType =

    type InnerType =
        member x.AMethod: FakeNamespaceName.AType2 = { AField = "test" }

type AType2 = { AField: string }

2. Load the file in FSI:

#load "test.fs"

Expected behavior

The file is loaded into FSI.

Actual behavior

FSI gives this error: test.fs(6,25): error FS0039: The namespace or module 'FakeNamespaceName' is not defined.

Known workarounds

• Don't use recursive namespaces with FSI
• Compile the code into an assembly and load that into FSI

Interesting,

namespace isn't really valid in fsx files, use module rec SomeNamespace. I can't really explain the rationale though, and I had never noticed this behaviour before.

c:\kevinransom\fsharp>copy con foo.fsx
namespace HelloWorld
^Z
        1 file(s) copied.

c:\kevinransom\fsharp>dotnet fsi foo.fsx


foo.fsx(1,1): error FS0010: Unexpected keyword 'namespace' in interaction


c:\kevinransom\fsharp>

And also:

Yeah, I wouldn't deliberately use namespaces in FSI. Its generated code though, so unfortunately I don't have a great alternative.
