Subject: Make listBindings return IO () instead of IO [()].
X-Git-Url: https://git.stderr.nl/gitweb?p=matthijs%2Fmaster-project%2Fc%CE%BBash.git;a=commitdiff_plain;h=dd0b3f0f95a335492533202a5801d7df9edd2762

Make listBindings return IO () instead of IO [()].

The previous type caused ghci to print an extra list of units after the
regular output, while it simple ignores the single tuple now.
