Subject: Re: Ant: [Caml-list] Efficiency of let/and
Date: Mon, 26 Sep 2005 01:24:20 -0400 [thread overview]

There is a small advantage in using "and" instead of "in let":
# let () =
let x = 2 and x = 5 in ();;
This variable is bound several times in this matching
# let () =
let x = 2 in let x = 5 in ();;
Probably the second "x" should have been a "y"... so the compiler catches
that mistake.
