Alternatively for small programs for which you don't use a Cabal file
you can use the PackageImports extension (-XPackageImports) and import
modules from specific packages. For example both the 'pool' and the
'resource-pool' packages provide a Data.Pool module. You can choose to
import the one from 'resource-pool' using this:
import "resource-pool" Data.Pool
