How do I see the type for operators in F# interactive? -

I am trying to explore types of operators such as :: F # interactive .

But I get these types of messages:

  unexpected symbol '::' expected in expression ') or other token   < P> Even if I call it  (: :)    
 
 
 I do this like this:  
  & gt; Inline showmecons A B = A :: B; Val Inline Showmans: 'A - & gt; 'A list - & gt; 'A list   
 or  
  & gt; Inline Shomapo B = A ** B ;; Val Inline Shomap: ^ A -> ^ B -> ^ A ^ ^: (Stable Member Pau: ^ A * ^ B -> ^ A)
