How does fsi.ShowDeclarationValues work?

Question

According to the MSDN documentaion:

When set to false, disables the display of declaration values in the output of the interactive session.

However, the following sample interactive session seems to contradict that summary.

> let x = 42;;

val x : int = 42

> fsi.ShowDeclarationValues <- false;;

val it : unit = ()

> let y = 42;;

val y : int

I was not expecting the last line above.

Have I misunderstood something? Can anyone confirm if this is a bug?

Thanks.

Answer 1

Looks to me that it didn't show the value in the last line, only the name and type of the binding.
