I am trying to dump out all function signatures exported from
System.Directory. I just tried
inside ghci: :! ghc --show-iface System.Directory. This is getting closer
... thank you! However, now there appears to be a "path" problem because I
get an error message: "System.Directory: openBinaryFile: does not exist (No
such file or directory)". ??
