There are two modules called the same name: System.IO.Strict, documented respectively at
    http://hackage.haskell.org/packages/archive/strict-io/0.2.1/doc/html/System-IO-Strict.html
    http://hackage.haskell.org/package/strict-0.3.2
 
My questions are:

1)    Will these two modules coexist in the same version of GHC? Or put it another way, both modules' .tar.gz files have System/IO/Strict.hs inside, will they overlap in physical disk? From where can I tell which locations they will be installed to?

2)    If yes, which module will "import System.IO.Strict" actually use?
