Expected Results: No error expected, code shouldn't print anything. If you change the second line of code with: seq { for node in [ 1 ] do yield! [ 1, format "9" ] } Then,you get an (unexpected): System.TypeLoadException: A type load exception has occurred. at fsi_0001+readval...@2[system.double].getfreshenumerator () [0x00000] in <filename unknown>:0 If you compile the code with F# compiler (fsc.exe), then it works.
