Subject: [Caml-list] Labelled parameter bug?
Date: Wed, 24 Aug 2011 18:49:00 +0400 [thread overview]
Message-ID: <CAMT7qiSwatTXz+nP7yrSect72C30VSARBufPt4Sr8mqEsmoMGw@mail.gmail.com> (raw)
The following fragment compiles without a warning but produces strange results:
let f ?(p1="p1") ~p2 p3 =
Printf.printf "p1=%s, p2=%s, p3=%s\n" p1 p2 p3
let _ =
f "p2" "p3"; (* 1 *)
let f2 = f "p2" in
f2 "p3" (* 2 *)
Outputs:
p1=p1, p2=p2, p3=p3 (1)
p1=p1, p2=p3, p3=p2 (2)
Why (1) and (2) are different? I assume f "p2" takes p3 instead of p2
but then the compiler should issue at least a warning...
