This is one example where having a REPL would help a lot.

That is how I check such types outside IDEs in other ML derived languages.

TBF, you can just do

    let _ : () = /* some expr whose type you don't know */

And compile it. It will quickly fail with a type error, giving you the full type of the expression.

Yeah, but it feels like a kluge, specially when used to F# on Visual Studio.
