:show packages does not list all loaded packages
GHCi's :show packages
seems to have bit-rotted, no longer listing all loaded packages:
$ printf "Data.Map.fromList [(1,2)]\n:show packages" | ghc.exe --interactive -ignore-dot-ghci
GHCi, version 6.12.3: http://www.haskell.org/ghc/ :? for help
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package ffi-1.0 ... linking ... done.
Prelude> Loading package array-0.3.0.1 ... linking ... done.
Loading package containers-0.3.0.0 ... linking ... done.
fromList [(1,2)]
Prelude> active package flags: none
packages currently loaded:
base
ffi-1.0

rts
Prelude> Leaving GHCi.
Note that containers
and array
are loaded when the call to Data.Map.fromList
is made, but the packages are not listed in the output of :show packages
.
If it helps, :show linker
does list the extra packages:
$ printf "Data.Map.fromList [(1,2)]\n:show linker" | ghc.exe --interactive -ignore-dot-ghci
