I'm appreciating the feedback. I discovered where I was going wrong. The library I was using allowed me to import a module, which in turn allowed me to use functions from other modules. So even though I could use func directly I couldn't use B.func because I hadn't explicitly imported B.
I find that interesting. I would have thought that if I hadn't explicitly imported a module I would either be forced to use the qualified name, not use the function at all, or at the very least be allowed to qualify the name. thanks Jason > -------- Original Message -------- > Subject: Re: [Haskell-cafe] namespacing? > From: "Duncan Coutts" <[EMAIL PROTECTED]> > Date: Wed, December 08, 2004 10:12 am > To: [EMAIL PROTECTED] > Cc: [EMAIL PROTECTED] > > On Wed, 2004-12-08 at 07:58 -0700, [EMAIL PROTECTED] wrote: > > I've got a general new person type question. > > > > I understand that I can hide a function in a module that I am importing > > if it conflicts with another identical function name. > > > > But if the situation arises that I would like to use two identically > > named functions from two different modules is there anyway for me to > > specify that I want to use the function from module A rather then the > > function from module B. > > module C where > > import A > import qualified A (foo) > > import B > import qualified B (foo) > > > ...
