Occassionally, Link causes a .NET error when changing a function or an operator #643

This is the error that pops up in the status window:

Void .ctor(Int64)
Void .ctor(Int64, System.DateTimeKind)
Void .ctor(Int32, Int32, Int32)
Void .ctor(Int32, Int32, Int32, System.Globalization.Calendar)
Void .ctor(Int32, Int32, Int32, Int32, Int32, Int32)
Void .ctor(Int32, Int32, Int32, Int32, Int32, Int32, System.DateTimeKind)
Void .ctor(Int32, Int32, Int32, Int32, Int32, Int32, System.Globalization.Calendar)
Void .ctor(Int32, Int32, Int32, Int32, Int32, Int32, Int32)
Void .ctor(Int32, Int32, Int32, Int32, Int32, Int32, Int32, System.DateTimeKind)
Void .ctor(Int32, Int32, Int32, Int32, Int32, Int32, Int32, System.Globalization.Calendar)
Void .ctor(Int32, Int32, Int32, Int32, Int32, Int32, Int32, System.Globalization.Calendar, System.DateTimeKind)

This is because of this line ([163] for me) in Link.Fix:

src(nsref U.Into)name nsref.{3 4∊⍨⎕NC ⍺:⍵(2⊃⎕AT ⍺) ⋄ ⍵}file

Because of the 2⊃ this relies on ⎕IO←1 in the namespace nsref is pointing to; if that's not the case, then a 0 is returned, which is an invalid argument for ⎕NEW DateTime, causing the error.

That means this can be fixed with 

src(nsref U.Into)name nsref.{⎕IO←1 ⋄ 3 4∊⍨⎕NC ⍺:⍵(2⊃⎕AT ⍺) ⋄ ⍵}file

I am on 4.0.17
