F# Deedle returns strange output of

Question

I am getting a strange output from Deedle when I use FirstKey and LastKey on a Frame of Rows. cl is a DataFrame in the below examples.

cl.Rows.FirstKey

returns: val it : (unit -> DateTime) = <fun:it@156-43> in the FSI window.

cl.Rows.LastKey

returns: val it : (unit -> DateTime) = <fun:it@157-44> in the FSI window.

I am expecting a Key Value of DateTime. Does anyone recognize the output? Do I have to do some kind of further processing to get useful output?

Update. I edited the question so that the complete output from the FSI window is now visible.

it is returning a function - just call it with `cl.Rows.FirstKey()` — John Palmer, Apr 08 '16 at 23:42

The comment by John Palmer has resolved my question. The correct way to code the FirstKey and LastKey function in my example(s):

cl.Rows.FirstKey() 
cl.Rows.LastKey()
