Well, that happens anyway with most packages since distros have to choose one set of flags that works. The proposal I was commenting on would just allow packages to depend on flags of other packages and so be explicit about this.
Consider this problem: * Package Foo has an optional instance, enabled with the --foo flag. * Package Bar wants that instance. * Package Baz doesn't want that instance, since it uses its own custom instance (e.g. yi's instance of Category for Data.Accessor.Basic.T, which clashes with the one added to data-accessor 0.2.1). * You want to install both Bar and Baz. Which one do you end up using? You can't have the same version of Foo installed twice (as far as I know anyway). It would be nice to have a separate namespace in exports/imports for instances so you _can_ selectively override them if you so wish, but that will probably cause other problems. -- Ivan Lazar Miljenovic Ivan.Miljenovic@gmail.com IvanMiljenovic.wordpress.com
