What did you do?

Imported the "debug/pe" package, called pe.Open("somefile.exe") or pe.Open("somefile.dll") and then called ImportedLibraries on the result.

What did you expect to see?

List of all imported libraries (I.E. []string{"kernel32.dll", "msvcrt.dll"}

What did you see instead?

[]string{}, even when the error is nil.

The body of ImportedLibraries is a TODO and returns literal nil values. You can obtain the libraries from ImportedSymbols with some text processing.
