# possible failure points:
# 1. Can't open dir due to bad path/permissions/whatever
# - easily simulated by asking the read_dir function to open a dir that
# doesn't exist, and is nested far enough in a path that it can't be
# created. /tmp exists, but opening /tmp/fake/path/whatever/dir will fail
# 2. Can't open dir because it's a file
# - create a file, try to read_dir on it.
# each of the above cases should be tested in all three failure modes:
# 1. quiet (no warnings, exceptions, or content)
# 2. carp (warnings, no exceptions, no content)
# 3. croak (an exception, no warnings, no content)
