Hi,

I'm trying to use xmlrpc module with hugs. The problems are not really related to this particulare module, so the question is here.

A module generated from the DTD for XML-RPC by HaXml contains import in the following form:

import Prelude (all, maybe, (++))

or something like that to avoid name conflicts with types of the same name defined in the module. In Hugs it leads to (:) not being imported into the module. Is there a way to import just (:) from the Prelude?

This one is tricky due to the fact that (:) is very special. I think various Haskell implementations differ on exactly how this is handled. I don't know enough about Hugs to say for sure.

Is there a way to import all but some symbols from some module?

Yes. You want the 'hiding' keyword, eg, import Prelude hiding (foo, bar, baz)

Is (:) a data constructor?

Yes.
