is that really as completely unobvious to you as your question implies?

    -- A
    module Main where
    import Data.Time
    main = print =<< getCurrentTime

    -- B
    module Main where
    import Data
    main = print =<< Time.getCurrentTime

given that package P only exposes a module Data (which, in turn, exports
a module Time), it appears that A behaves as if it was B. is that intended? 
or is something else going on? which is what Ian was asking about, wasn't it?

no offense intended;-)

as long as we agree on the features we want, we don't need to
agree on whether their lack is a flaw or a miss.
