Subject: [Caml-list] List.fold_left vs. Hashtbl.fold
Date: Tue, 27 Nov 2012 23:40:04 -0500	[thread overview]
Message-ID: <50B595A4.50402@wwayneb.com> (raw)

List.fold_left expects the List as the 3rd parameter with the second 
parameter being the initial value.

Hashtbl.fold expects the Hasthbl as the second parameter with the 3rd 
parameter being the initial value... just the opposite of List.fold_left.

Is there a reason for this difference?   I'm having trouble remembering 
which goes which way.   If it's not a historical accident, I'd like to 
have a understanding of why they are different to help me know which is 
which.

Thanks,

Bill
