Subject: [Caml-list] Total application of function with labels
Date: Wed, 5 May 2004 17:18:22 -0400 [thread overview]
Message-ID: <20040505211822.GA23376@cs.brown.edu> (raw)
Total applications of functions with labeled arguments will work,
even if the actual arguments have no labels. So if you call
let my_a = ... in
let my_b = ... in
f my_b my_a
it doesn't matter whether you declared
let f (a:int) (b:int) = a * (b + 1);;
or
let f ~(a:int) ~(b:int) = a * (b + 1);;
and none will save you from the bug of passing the arguments in the
wrong order. A bug like this cost me a few nights of sleep a while ago.
Is there a programming convention that would "enforce" labeling the
arguments in a total application of a certain function?
Thanks,
-- Manos
